... Me and my bf had sex saturday for the first time{im nt a virgin thou}when we were doing it I felt a really uncomfy pain a horrible sharp but dull pain,he is bigger than average{8 1/2 inches}and he was going insanely deep and i LITERALLY HEARD A "POP" SOUND all i felt was pain pain pain it started to bleed a little while after and my vagina was sore for 3 days.i told him to slow down and he did but it wasn't about how deep he was going because his penis just naturally hurts.what can i do to ease the pain? my vagina is 4 inches long and he put all 8 1/2 inches in ,was he hitting my cervix?
