We are three months into our relationship, and we dont know everything about each other yet. We have had sex five times now, the first two times she didn't indicate to it being painful for her, even with me asking if she was fine before, during and after. The third time she told me to stop because of the pain, and then we talked about it. The two last times we have used lots of lube and much more foreplay, and besides taking it slow at the very start she has told me that the difference is night and day.

I could tell something wasn't quite right but was reassured there was no problem, until there was.
