i don't want to go to the ER

I want to stay anonymous because I'm embarrassed... I had sex with an idiot yesterday who clearly doesn't get much vag let alone FTM vag ... anyways because i wasn't very lubricated down there and he tore my skin ... better known as vaginal laceration ... I don't want to go to the ER for obvious reasons and don't know what you really do ... has this happened to anybody? What did you do?
