  • Posted The Masturbation Gap--What Women Can Learn from Men's Masturbation Habits to The Sex Doctors are In!
    Recently, I conducted a study in collaboration with Good in Bed on penis perceptions. Though the study covered a wide range of penis-related subjects--including size, self-image, erectile dysfunction, and premature ejaculation--I found particularly interesting the statistics that highlighted a masturbation...
  • Commented on Uncomfortable with riding
    If that position makes you uncomfortable, then I don't see any need to integrate it into your sex life. Unless it is something your partner would really like or there is some other reason you really want to be in...
  • Commented on What are the chances of my ex-girlfriend being pregnant?
    Hey Michael. Although the pull out method isn't the most reliable method, it also isn't awful. Around 22% of people who use the withdrawal method sometimes correctly but sometimes incorrectly will get pregnant in a year. If you are amazing...
  • Commented on My bi side
    You are not a small minority as a bicurious man. There are lots of you out there! Sexual attraction is super fluid, in men and women. And you're experiencing that fluidity right now, which should be celebrated. I think it...
  • Commented on Starting a relationship with delayed ejaculation
    I find it very promising that your partner is seeing a sex therapist about this issue. Delayed ejaculation does have some promising treatment outcomes, so this isn't necessarily a case of him having sexual needs that aren't going to be...
  • Commented on Should I give up trying?
    Giving up trying is not going to get you where you want to be. It sounds like you would like to have sex more frequently and perhaps engage in longer sexual sessions with your wife than the two of you...
  • Commented on Is this okay?
    Some people like watching porn, like yourself, and it gets them very excited and turned on. However, for other people, like your husband, it just doesn't do it for them. It is totally fine and "normal" either way. The two...
  • Commented on Good nudes, bad body?
    First of all, no one is perfect. And anyone who expects perfection out of their partner isn't ready to have a serious meaningful relationship. So I think it would help you to take the focus away from striving for perfection....
  • Commented on Sexual advice
    In addition to Ian's question regarding masturbation, I'm curious whether you have yet to ejaculate during intercourse? Is the sensitivity a negative thing where it feels like too much stimulation to the point where you can't ejaculate and have to...
  • Posted An Interesting (And Sexy) Trend From Our Latest Survey to Sex Trends
    One of our missions at Good in Bed is to try and change the statistic that CNN reported, indicating over 40 million Americans are stuck in a sex rut and more than half are dissatisfied with their sex lives. This...
  • Posted What Are Your Attitudes About Valentine's Day? to Sex Trends
    It's Valentine's Day - the day of pink and red explosions of chocolates, roses, and teddy bears everywhere you look. To some, this is an exciting time; a holiday looked forward to with anticipation. To others, this is a...
  • Posted Learning From Lack of Orgasm to Sex Trends
    I've always kept track of all of the questions that readers, students, and acquaintances ask me related to sexuality and relationships. This morning, I was reading through some of the questions, and noticed a theme of orgasm throughout. Most of...
  • Commented on about pregnancy
    I second Dr. Kerner's response above. However, if you still want to engage in that form of sex play, use a condom or release the sperm elsewhere so that you can minimize the chance of the sperm entering the vagina....
  • Commented on Herpes
    I think that WD is right on here. This isn't even really about Herpes at this stage and is more about why she is putting a stop to your sex life. There are plenty of couples where one member has...
  • Commented on My Girlfriend's Anorgasmia
    You say that you've "eaten her out correctly" - but unfortunately, there is no "correct" way to give oral sex. Every woman is different and preferences vary widely. Ask her what she likes...keep the lines of communication open during sex....
  • Commented on after sex
    There shouldn't be anything about this that will hurt you, aside from the pain that you (or is it her, like WD asked?) experience. So, if you don't find the pain is severe or you're fine with feeling that moment...
  • Commented on I Think My Wife Doesn't Find Me Sexually Attractive
    I do think it is incredibly important for the two of you to talk about what is going on. Something isn't right in your relationship if this is abnormal and you're left feeling neglected. If you could talk to her...
  • Commented on Soreness after Sex
    I'd be interested to know where the pain is located? Is the pain at the vaginal opening? On the upper inner thighs? The cervix? Knowing where the pain is may help determine what it might be. Do you use lubricant?...
  • Commented on physical attraction
    Does he know you don't find him physically attractive anymore? I don't necessarily think it will help to let him know, unfortunately. And if you do make comments about it to him, try to sprinkle them in with positive things...
  • Commented on How to keep a woman from thrusting away during orgasm
    Although you are looking for advice about how to maintain a position, I'm going to offer something a little different. Once a woman experiences orgasm, the clitoris can be incredibly sensitive. Women vary a lot from one another in terms...
  • Commented on ejaculation during intercourse
    Since you can ejaculate during masturbation, I would like to eliminate any sort of physical causes of this, but I'm not entirely satisfied with that, so I would suggest you visit an MD in your area who has experience in...
  • Commented on crying in relationship--why?
    If you hadn't added the last sentence about him leaving the country, I would have been at a bit of a loss as to why you were crying other than to chalk it up to emotions related to being in...
  • Posted Relationship Boredom to The Sex Doctors are In!
    Good in Bed Research recently conducted a survey to examine relationship boredom, and according to 3,341 readers in committed relationships, half reported either being bored or on the brink of boredom in their relationships. Further, 24 percent of people reported...
  • Posted Infidelity & Monogamy: What's Going On? to Sex Trends
    Arnold. Ashton. Anthony.  When it comes to the ABCs of infidelity, one thing is certain: It's only a matter of days - maybe minutes - before another extramarital scandal rocks the headlines. With brand new stories of celebrity and political...
  • Commented on Problems with Sexual Desire/Arousal
    From what I can tell based on the information you've provided here, what your experiencing is a perfectly natural reaction to the circumstance you are currently in. You're stressed, buying a house, taking birth control, recently moved, tough time at...
  • Commented on The Bro Code
    This is tricky. When it comes to my friends, I always try to put myself in their shoes and think about how I might feel if I were in their position and found out. If you are okay with that...
  • Commented on Toys for Practicing cunnilingus w/o partner
    I'm certainly not here to give you a strange look - good for you for wanting to brush up on technique for your partner before "the big day". However, good cunnilingus can be had without any sort of speech therapy....
  • Commented on Hand jobs
    A hand job is very safe. One of the safest, actually. However, there is bodily contact since her hands are touching your penis...so she could conceivable get something from you if she were to get semen on her hands and...
  • Posted Who Believes in Soulmates Anymore, Anyway? to Sex Trends
    In a world of technological advance where we have as much access to people across the world as we do across the coffee shop, where romantic options are presented to us online as often as they are in person, it...
  • Commented on mirena and sex
    I suppose the strings from Mirena "can" get caught around the piercings, but it is doubtful. It really depends on how short the strings are cut. Your medical provider can cut those strings short to ensure that this won't happen,...
