Hey im 19 and this has only happens to me once and only with this one girl during sex I go in it feels as if her virgin is cutting my penis and my forskin gets pulled back and after sex I pull back my forskin and I have deep cuts on my penis but they heal after a 2 weeks or so I dont know what's happening
Could be a tight foreskin? did you try working with it? pulling i back abit, then waiting and repeating?
It sounds as though you broke her hymen. I doubt that this will happen again with this girl.
