i recently had sex with my fiance and had a bad lower abdominal pain while having sex.
when i was on top i could feel like pressure inside. kind of like i had to pee realllly bad but it hurt. so i told him to stop and he could try on top. it was fine until he propped my legs up i felt it even worse.

its almost like the deeper in my canal he went, the more painful pressure i felt.

i just wanna know from people who are studying this stuff or personal experience.

no guessing please and no stupid poking fun.
this is a serious issue and i would like a serious answer please.
thanks.
