Sex / orgasms

sagee

I can’t have orgasms with my partner anymore. Like it just can’t work like it used to... it used to be great and now it’s terrible sex.. I’ve tried for over 45 min have an orgasm and nothing happened except me getting muscle cramps from tensing to hard lol any advice? Or tips...? I’m 21 years old and miserable when the sex question pops up because I can’t enjoy any of it..
