Sex problem in my relationship?

[connie t]

I have been dating my "friend" for about a year now. In the beginning everything was fine but lately (past 4-5 months) I haven't been able to orgasm. I have never had a problem before. In my past relationship my partner would give me oral. He doesn't do oral, if he does he doesn't show it. He knows I don't orgasm and I feel used. He did surprise me the other day and went down. He didn't really know what to do. At this point I don't know what to do? I need to orgasm...
