There is a strange problem: My girlfriend 'bleeds' whenever we have sex except it isn't painful and there isn't a lot of it. It isn't even red. It's a pinkish substance and its ruining my sheets! It isn't a lot...usually they're in ~4cm x 1.5cm puddles/stains. Is it blood? Or something else? Last night after sex There was something stuck to my bum. I took it off and looked at it and it was a clot (I think, she said it was although it looked really weird, almost transparent although did have a fleshy look and pinkish tint). What's even stranger is she was on top so I have no idea how that got on my bum cheek. Does anyone know what this is or has anyone experienced it before? What is the pink goo?
