Why won't my boyfriend sleep with me?
	
	
		My boyfriend and I have been together for 6 months now.  I know it's crazy but we moved in together about 2.5, 3 months ago.  The first month or two we went at it like 2 three times a day.  But for the past two, nothing.  Nothing at all.  I try to touch him and he won't let me.  He kisses and is very affectionate but nothing else. 
 We have a great time together; we go out and party, we laugh, wrestle, joke.  Everything is great aside from that.  He has asked to marry me on numerous occasions and wants me to meet his parents that live across the country in January.
He has a bit of an alcohol issue and sometimes other activities.  I ask him about the problem and he just says he doesn't know why he won't be with me.  The past few times I've asked or commented; he just blows me off.  He even laughs about it.  He's accused me of cheating and I blow him off.  He's gotten erections but won't let me touch him even then!
I'm completely and utterly frustrated.  Two months is a long time for someone who sleeps with a man every night.  He's only 31. (I'm 28)  I've gone over so many different situations: is he gay, am I unattractive (totally not the case), is he cheating... I don't know what to do.  I want to buy some new lingerie or just grab it but I'm afraid of being rejected.  I don't want to dump him over this; he is a great guy but if something doesn't break soon, I have too.  Someone help, please!
