Dear Dr. Klein, I asked my boyfriend the other night about his sexual past. So far he's only had one serious relationship before me. I was ok with talking about it at first. I was excited to find out about his past. He didn't want to talk about it because he said that it wasn't healthy to ask these questions if I'm not ready. But eventually he told me about his past. Now I feel like maybe I shouldn't have asked him. I feel like I don't please him as well as his ex-girlfriend. I'm putting myself down because I feel he has done more with his ex than with me and I feel that I may be and amateur for him. What should I do? I don't like feeling like this because I do realize that his past is his past and I shouldn't worry about it. He says that he enjoys it with me but I still feel self conscious.
