Love life

So I have been with my bf since April although we've been talking longer then that, I never really kept up with dates because I didn't think it would be anything more then friends well fuck buddies. Everything is going great and I mean TO EVERYTHING. EXCEPT the fact that I get sore easily when were having intercourse...it really irritates me, cause I don't want him to stop but if he doesn't it'll hurt, anyone else experience this??
