Last night my girlfriend and I were going at it pretty hard... she was riding me like a good cowgirl should. Well she likes to lean way back and sometimes it's a little painfull but nothing I've ever worried about.. Well afterwards I was noticing I was a little swollen. Well this morning I wake up and I'm completely bruised. It's like she broke my 'main vein' on top of the shaft. Is this something that will just go away and will just take time or should I get this checked out?
