My boyfriend doesn't want to have sex with me
I've been with my boyfriend now for 3 months and we have only had sex 4 times. The last 3 times however he has pre ejaculated which has left him very embarresed and apologetic. I reassured him that its OK and I don't mind, I'm here for him no matter what however he is still embarresed. Since the last time this happened which was 4 weeks ago, he has not tried to have sex with me or touch me and last night when I was kissing him he just said he was tired. I know from what I've heard that he has slept with a number of people and I am the first person he has had the pre ejaculation problem with. I understand that this maybe the reason he is advoiding sleeping me with but its beginning to get me down and its making me doubt myself and feeling like he isn't sexually attracted to me after all. In past relationships I've had I've had a very healthy sex life and although I want to be therefore him completely its really beginning to get me down and I really don't know what to do or how to bring up the subject with me without putting even more pressure on him to perform. Please help
