(NSFW) part of my body is numb, any idea why?

Numb is not good. It indicates a nerve problem. See a doctor.

Yeah, will do.

I agree with @Rock2

This could be nothing more than a very thick wallet in your back pocket ( no, I am not kidding ), a lot of bicycle riding, sitting with lousy posture, or something much more serious.

Were you biking for a long time? Haha numb nuts, nice.

Check out pudendal nerve entrapment.

My sister’s hands were numb and tingling the other day, she was also very hungover and eventually fainted. It was dehydration, the feeling came back after several glasses of water. Perhaps this is what you have/had.

Sounds like you pinched a nerve

Thanks for the responses everyone, turned out to be related to a high school wrestling injury. I’m okay now.
