I know I asked.. I wanna make sure.?

alright. i went and got put on birth control. the next day, i moved in with my fiance and everything. well, we were both virgins. he popped my cherry which hurt a little bit and then he went in a couple times and he left it alone because i was hurting. well, last friday he did it again and it was all fine and dandy until he put himself all the way in and i felt like he was hitting something. it felt like someone with long fingernails pinching the sh*t outta you. well, tonight we tried it again and sometimes it would hurt, but sometimes it wouldnt. when he would spread my lips it would hurt too. is it just because im new to the whole "" thing? if so, is there anything to help with the pain? tricks, meds, etc? please help. i dont mind pain, but i hate it down there. & please be mature about this, seriously. thank you!
