My boyfriend lasts an hour or more when we have sex, after he cums probably an hour later I start cramping. Like I can’t walk ! What does that mean? What can I do to prevent that? I’m flexible enough to do ridiculous positions with him, I don’t understand why my muscles are cramping! :(

See a doctor about it, or it might just be because you are doing to much. Take a break if you can in between. Or take some medicine for muscle cramps before having sex.
