So it's my birthday and my girlfriend decides to wake me up the right way by jumping on my cock. Afterwards, I noticed I had a little pinkish blood on me. I asked her about it and it turns out that she's bled like this nearly every time we have sex. She says it doesn't hurt, but I wanted to ask the women here if this sounds familiar at all since I'm not sure that it's normal. I'd believe her when she says it's no big deal but I kind of think like 'it's blood, how can it not hurt?' and I don't want her to be lying about it just to make me feel better. I figure it can't be an infection or something temporary because it's apparently been happening for two plus years. Any ideas? Should she see a doctor?
