I went to a party and I had on denim colore leggings. I was dancing on a guy.
Should I be worried about pregnancy/ semen seeping in through my leggings?

No.

When you said you where "dancing on a guy" what do you mean?

If you were just dancing, not having sex, than there's really no need to be worried about pregnancy. If you were dressed, than you obviously didn't have sex. If for some reason he ejaculated while you were dancing, it's not likely that it would seep through your leggings. Was he dressed as well?

Do you know how pregnancy happens?

Lol thanks

Ohhhh lol thanks.

Girl I think you aren't pregnet... but watch out because some people say sperm has legs maybe it got in or maybe not just buy a pregnesy test...
