Thread: why does having sex 3 times in a row hurt??

me and my boyfriend like to have sex several times in a row, the third times usually hurts... why??

It sounds like the skin is irritated or chafed at that point.
I also notice that there isn't as much natural lubrication the more often or longer that sex is.

I would try some K-Y, and maybe take it a bit slower the third time.
