My bf doesn't want to have sex with me......

Am

Okay, so my man and I have been together for 2 years and lived together for the last sixth months. I just graduated from university in May while working full time. Which you can imagine put major stress on me for the first year or so of our relationship. The amount of stress and things to do I had, made my libido very low or we simply never had the time to have alot of sex. But now that has changed and we have time, and I'm not stressed anymore I'm constantly throwing myself at him to no avail. I feel like its worse than when I was stressed and busy. Like living together has ruined our sex life. When I've talked to him about it he claims hes just gotten so used to me not being around thats hes fine with not having sex. It makes me feel like hes nit attracted to him, I tell him that and he says he still thinks I'm sexy and that I'm the only one he wants to be with he just doesnt want to have sex 8/10 times I try. Any advise ladies?
