I am 17 years old, and I have been with my boyfriend for over 18 months. About 6 months ago we had a big discussion about sex. We both said we were ready and would like to. I asked my mother to put me on the pill and my boyfriend bought condoms. However when the opportunity arised, it was extremely painful and from what I have heard it shouldn't hurt that much. The other problem is that no matter how hard we tried, or how hard my boyfriend pushed, it wouldn't actually go in. At first I thought maybe it justs hurts more for me, everyone is different, but once I ended in tears and is was trying to force it in, I started to get concerned. Do you know what this could be?
