So I need some advice. Me and my fiancé tried to have sex the other night and I was in so much pain it burned it hurt. It felt so tight like it legit wouldn’t fit inside me like I couldn’t make it go in. It felt like my vagina sorry tmi but was like closed and I couldn’t get him inside me. Someone please help me I need to know how to fix this. I feel he is getting aggravated with me. I feel he is being as patient as possible but he is a guy and I feel bad that I can’t do anything to help him cause I know he wants to have sex. we’ve tried lube and taking it slow but it’s just seriously kills and idk if it’s normal or not. Someone help me. It kills me to thinking having our son might of ruined our sex life.
