Special yet? 😪

So, today my bf and I were talking   about different things about our relationship and we ended talking about sex. He and his ex dated  for  over a year and he told me that they did it but just once, because she told him that she wasn't ready yet and didn't wanted to do it anymore. He told me that like 3 months ago, but today he told me that it wasn't true and that the did it many times. I felt like a little bit jealous or hurted not because he lied, it was because I felt special in a certain way because he was my first... And I used to think that everything we have done until know was new for both of us, but rn I don't know what to think. Do you think I'm exaggerating?Â
