Girl,
I was there. My boyfriend (now husband)had 3 lovers before me. I was a virgin and of course I always think about those 3 girls. He never talks about them not but when we first started dating, I had asked questions about them because I wanted to know. Now, I kind of wish I didn't ask because his answers are still stuck in my head after 3 years. One girl used to swallow and I would never do that so I've always wondered if he liked her more for doing that. That same girl used to always be on top because she liked to be in control, but I like it on the bottom because I like the feeling of him being on me. Lately he always wants me on top because he says he likes it better but I like the bottom. I know it has nothing to do with that ex but that thought is still in my head. He tells me he doesnt even remember them anymore and even that his first was "EWW SUCH A BIG MISTAKE" but who knows.
Its a tough one. I love having sex with my man. But sometimes sex is un-needed stress. I got pregnant, God knows what diseases are out these days, you don't want to be compared to the ex's, etc.
My mom waited 4 years to have sex with her highschool lover and then the chase was over and he broke up. Sex is nice but it's up to you. Sometimes it can change a relationship for the worse. Good luck!
