My boyfriend will not have sex with me.

This sexless relationship is killing me emotionally. I feel I can't trust him because he could be wanting someone else and putting his other time into that instead of actually having sex with me. This trust issue is about him telling me things. He seems bottled up. His constantly talking and flirting with other girls on Facebook and on mobile.

I don’t think he is cheating, but his getting satisfaction from something or someone else. I’m keen to make our sex life more interesting and he seems to like that idea, yet he doesn’t seem to be doing a damn thing about it. I’ve even made many suggestions on a threesome as id love to experience that as I have already had sex with a woman. I’m not a prude in that way and believe I can trust him to stay with me. As his had many girls in the past his been “emotionally detached from” (Those of whom he didn’t live with.) I however do live with him and moved state because he wanted a relationship with me.

I know he cares about me a lot and loves the companionship of the relationship. But yet when I initiate sex he doesn’t touch me and when I ask why he doesn’t want to have sex he says “he doesn’t know” I've stopped giving him oral in the hope he'd want to have sex. Its been a month and he still saying “I don’t know”..

I’m trying to understand this, I am an attractive woman. I'm feeling depressed.
I need help :(

Did you ask him if he likes men? Well from your question, it seems he is not. Here are my subjection; just leave him alone for a week or two, don't ask him or border him about sex. Dress sexy and focus on yourself and pay a lot of attention to him but less to sexual advances.

If he doesn't know you tell him he better damn well find out. Wonder what else is going on besides lack of sex? Any changes in circumstances like job, health, or new kids?

No, his definitely not gay. I actually decided yesterday to focus more on myself and looking sexy and being more happy. I've tried letting the subject go with no sexual advances for 4 weeks, then I thought id bring it up again witch has led me to this point. His still very affectionate, cuddles every night. Just not intimately.

He did say he felt trapped because he couldn't sleep with other woman?
