Okay. Bare with me, I'm sorry if this is super descriptive.

So my boyfriend and I had sex for the first time. He broke my hymen on the first time a few months ago but I was too scared and he didn't actually insert it completely, but this time it was finally successful and we actually "did it". It was doggy style, but I was bent over a table so maybe the angling was bad(?) I don't know.
Anyways it was painful, during it I felt this intense pressure towards the back of my abdomen. It's hard to explain, but it basically felt like he was hitting my intestines (I know that's probably not what was actually happening haha, but it's what it felt like

) and like i needed to "go" (But didn't actually ) Once he finished, I felt no pain and it was normal. I feel like it only hurt when he went deep. Maybe he was hitting my cervix? But I have no idea if that's what it feels like.
Sorry this turned out freakishly long and annoying to read.
Thanks a lot!
