- Rabbit Habbit®
A famous sex toy that features a vibrating dildo designed to target the G-spot; rotating beads that massage the introitus; and tiny rabbit ears designed to provide powerful stimulation to the clitoris. The Rabbit Habbit, made by Vibratex, was first popularized by the television show, Sex and the City.
The act of forcing another person to engage in intercourse without his or her consent. Rape may be perpetrated by a stranger or, more commonly, by someone who is known to the victim, often a romantic partner. Males or females may be victims of rape. Rape is a form of sexual abuse and is a risk factor for sexual dysfunction, no matter when it occurred. (see sexual assault)
A seam-like line where two symmetrical organs or tissues of the body fuse together. The vertical line on the underside of the shaft of the penis and down the center of the scrotal sac is referred to as the penoscrotal or scrotal raphe. During the first trimester of fetal development, the female and males sexual anatomy is formed from the same tissue as a result of the absence or presence of certain hormones. For example, the labia majora in females fuses together in males to form the scrotum.
- rapid ejaculation
An intercourse position in which one partner enters the other from behind. Many variations on rear entry are possible, including the well known "doggy-style," in which one partner is on all fours, while the other partner stands or kneels behind. Rear entry positions allow for deep penetration, and may be used to target the a-spot, G-spot and p-spot. (see facedown rear-entry, rear-entry with a pillow, spooning)
- rear-entry with a pillow
A rear-entry intercourse position in which one partner lays facedown on a pillow while the other partner penetrates from behind, so that neither partner is required to support themselves on their knees or standing. (see facedown rear-entry)
The last portion of the large intestines, which connects to the anus to transport feces out of the body.
A traditional Chinese medicine (TCM) technique that uses massage to activate various pressure points on the feet, hands and ears, with the intention of healing a variety of physical and emotional ailments. (see also acupuncture and acupressure)
- refractory period
A period of time occurring immediately after ejaculation in which a man is physiologically unable to get another erection. A refractory period may last for minutes (typically among adolescent or young adult males) to several days in older men. During adulthood, a man's refractory period commonly lasts several hours, though it varies considerably among men. Women do not experience a refractory period, which is why some are capable of multiple orgasms.
In humans, the process of the ovum joining the sperm to create offspring. Fertilization can happen through unprotected vaginal intercourse or through the use of assisted reproductive technology like in vitro fertilization.
- reproductive organs
Parts of the internal sexual anatomy that are involved in producing offspring. In women they include the ovaries, fallopian tubes, uterus, cervix and vagina. In men they include testicles, epididymis, cowper’s gland, seminal vesicles, prostate gland, urethra and penis.
- resolution phase
The fourth and final phase of the sexual response cycle, developed by Masters and Johnson, in which the genitals and the body return to their pre-arousal state. During the resolution phase, vasocongestion dissipates, and erection, lubrication and other physical markers of arousal subside. The resolution phase generally occurs after ejaculation, orgasm and/or a loss of arousal. The resolution phase is preceded by the excitement phase, climax phase and plateau phase. There are conflicting theories about the sexual response cycle. Researcher Helen Singer Kaplan proposed Kaplan's triphasic model starting with sexual desire, while researcher Rosemary Basson proposed that, for women, sexual desire often happens after arousal.
- retrograde ejaculation
A condition in which semen moves backward into the bladder rather than out the urethra during ejaculation. Common causes of retrograde ejaculation include: surgery for prostate cancer or other pelvic surgery; nerve damage from diabetes; and certain medications, including anti-hypertensives and anti-depressants. Retrograde ejaculation is not dangerous, but can be a cause of infertility in men who are trying to conceive. The use of anti-histamines may improve retrograde ejaculation. Men who practice Tantra to experience multiple orgasms may, in some cases, be experiencing retrograde ejaculation.
- retroverted uterus
A condition in which the uterus tips backward in the body. Symptoms of a retroverted uterus may include: dyspareunia; dysmenorrhea; incontinence; urinary tract infections; and, in rare cases, infertility. Some women are born with a retroverted uterus, while others develop the condition as a result of childbirth or menopause; or scar tissue from endometriosis, pelvic inflammatory disease or fibroids.
- reverse cowgirl
An intercourse position in which one partner sits on top of the other, facing the other direction. Reverse cowgirl can be a variation of woman-on-top.
- rhythm method
A method of birth control that counts the days of past menstrual cycles to predict ovulation and prevent pregnancy. The rhythm method has a high failure rate, since most women's cycles vary from month to month, and it does not protect against STIs. (see FAM)
A type of anal stimulation in which one partner uses the tongue and/or lips to stimulate the anus of the other partner. Rimming generally occurs as a part of oral sex and may be practiced by men or women of all sexual orientations.
- role playing
A form of fantasy play in which partners act out roles and/or get dressed up before or during foreplay, intercourse andother types of sexual or social activities. Role playing may or may not involve a fetish.
A pill prescribed to induce abortion before seven weeks (counting from the first day of the woman's last period). RU-486 blocks progesterone and induces contractions of the uterus. RU-486 is often incorrectly confused with PlanB®. See mifepristone.
