hi, me and my girlfriend had sex last night and when she got home she noticed a bit of blood in her underwear and the noticed a cut about one inch long near her clit. we are both really really confused as we are not sure how it happened and it didn't hurt her but it is quite a large gash. i presume this should heal itself? is the anything else you could suggest for it? we don't know how it happened but at one point the penis came out t quite hard, do you think it is possible that that could of torn the skin?
