It’s so painful..... 😖

My bf and I have been trying to conceive for 2 months now and I started noticing it awhile ago but now that we have sex a lot more I notice it way more! I get like a jabbing pain inside when we’re having sex... and idk if maybe I just can handle him (he’s a very good size sorry tmi) or something is wrong with me! I know I have no infections or anything I just got a pelvic exam just before trying! It just kinda feels like my walls are getting hit. And sometimes I’m just wanting my bf to hurry up so he can get out of me! I heard something about like a slanted uterus or something that can cause pain during sex but I’m not sure.. do any of you have problems like this?? Please help!! Any responses with help!(:
