Having a low desire for sex (low libido) may be attributed to low testosterone. Having low desire for affection, or for being affectionate, cannot be attributed to low testosterone.
You say he has a stressful job in law enforcement. I've counselled a lot of law enforcement professionals, and I want to raise a different possibility: depression.
Male depression often does not look like female depression. It can often be masked by anger, withdrawal, irritability, aloofness. If he's working shifts, that can be a complicating factor, as shiftworkers are more depression-prone than day workers. Poor or disrupted sleep from any cause is also a factor in depression.
It would be worth mentioning this to his doctor. Depression can severely impact overall health and performance, and increases risks of accidents and errors in judgement.
Best of luck.

I know how you feel. My husband and I have been together for 12 years, married for 10. We have a lot of fun in the bedroom, but outside of there he is cold and aloft. I don't get a kiss goodbye, no I love you, no consideration or appreciation. It's hard and hurtful. I talk to him about it too but I never get a response either. Just a stare, a shrug or the ever popular "I don't know" answer to any question I ask. I just try to stay positive and give him time to figure things out. That's all I feel I can do at this point, I don't want to give up the fight. Good luck with it all.

I want you to remember that he does have a stressful job, so remember that it is not about him not wanting you its probably more of him being physically drained at the end of the day. Does he ever have days off from work? Maybe one of his days off you can schedule for the kids to go to a daycare (or to a babysitter) and have the day with just you and him. When you do schedule a day like this, start off in the morning with sex. Testosterone is highest in the morning, so he will probably have more of that drive to want to do something. So, right when he wakes up you are going to want to plan to do something sexual. This could be some intimacy in the shower, waking him up by caressing his body, or having breakfast in bed (the naughty kind with strawberries and whip cream). Make sure you also plan ahead for a day like this so as to pick out something sexy for the evening to wear. Something that will make him want more of what he had to taste in the morning. I hope this helps.

Couples counseling, with a therapist who works with cops, soldiers, etc. Your husband needs to speak his truth and you need to hear it. I'm guessing a male therapist will help your husband open up more.
Time for some very brave communication. Good luck.

Thank you for the help. Its really hard feeling alone especially when your married! He works 12 hour shifts so on his days he works I never approach the issue, but on his days off I feel as though it's our time to reconnect and be one again. I handle EVERYTHING from bills and taxes to groceries and shopping. I ask nothing of him when he walks in the door because I know his job is very high stress. I just need to feel as though I'm desired and wanted. I'm in really good shape if I say so!! =) I take care of my body to look good for him. . the only down side is my breast size. After breast feeding for 3 years I have little left. I was once very large and now due to lack of body fat and breast feeding I'm small. I thought maybe that had to do with him, but he says not at all he just doesn't feel like himself lately. I will bring up the subject of a therapist this weekend and see how he responds. We are great as a couple. . very open and honest just need help with this issue

I feel compelled to comment for 2 reasons. 1st, my husband is also in law enforcement. 2nd, I've been exactly in your place around your age (I'm 47 now,married 27yrs). 6 mths ago my hubby shockingly told me that during that time he was cheating with a "cop chaser" {nice phrase for women who persue cops whether married or not). At the time I was clueless. I am not at all suggesting that yours is, was, or could be cheating, but I feel in a some way mine cheated because of a variety of stressors~one being the job. I believe the stress of him dealing with the affair after it ended caused him to be unattentive. My hubby has never been as affectionate as me & I finally resolved that it's just his way. Sad. We all want to feel sexy, loved and adored by our men. Things are much better for us now these days. Couseling may be a good idea. You sound truly in love & want to fix things. If you would like to discuss privately issues of being married to a cop, I can leave my email. Good Luck

CC thank you very much for your response. It is very hard to be married to man in this field. It has alot of unknown stressors that most dont understand. At first I did think affair. . .but there is no evidence. I'm not saying it isn't possiable but I highly doubt it. He goes straigt to and from work and doesn't have really any time in between. He really is a family guy but we have had alot of stress at home as well. Our 4 yr old just underwent open heart surgery and I think this is the main contributor. He internalizes alot and I think this may have put him into a depression. As a man in law enforcement, they really look at depression and he is scared to see someone for it. We are very close and have talked openly about cheating and he knows that it is absolutley a deal breaker. I would leave him instantly and he knows that. He would as well if I cheated. He is very loyal and honest to a fault, but I guess you just never know!!!!

Also, I know what you are talking about "cop chasers" For some reason women love them. . .it's sad what women do these days. We've been married since 19 and eachothers one and only. I'm open to do anything in the bedroom as long as it's just us. . nothing is off limits to me since we've agreed to be with one eachother. I just get concerned about him because of the change in the past few months. We did have a big converstation and he has been trying, but I know everythig isn't okay with him. I really feel as though he is going through something right now and can put it into works what he is feeling. I know having the multiple surgeries and long stay in the hospital has been rough on all of us. . .maybe he just took it differently as where I got upset, and then mad and ultimately just had to deal with it. We've had alot of hardships health wise. . I had cancer at 21, both pregnancies threw me in the hospital and almost cost my life and now this. . .I think he just needs some help!

Wow, your family seems to have had more than your fair share of stress related issues. I really hope you and DH can get things worked out before too much time elapses. Communication is so important. And seeing a professional might really help. It's probably just a phase. I wonder if he's thinking too much about where he is in his life;i.e., career, family, realtionship, all the health issues you've all had to deal with, etc.

I really do wish you all the best and hope you and DH can get on the road to a more mutally loving relationship. Keep us posted on the progress.

For finding a therapist, I'd recommend you try going to the AASECT website (dot org) and click on the middle left "in your area" link for more drill down. I, personally, like a woman sex therapist because she understands better what its like for the woman--which in my case is where a lot of the therapy is needed (not 100% the female partner, obviously) and I actually feel more in the moment talking about sexual issues with a woman--your guy may much prefer a male therapist. They may recommend each of you go separately to see them before joint sessions. What happened in my situation. You can find some who will let you "phone it in". Creating awareness and a safe space where talk about intimate issues is what its all about for me. I prefer face to face meetings. I actually found our therapist while reading comments to an Elle magazine article online about "Sexless Marriages". Sometimes its a thin thread that holds the elephant.
