So sex ed was really bad where I'm from and I've had to figure a lot of shit out by trial and error. I've been enjoying experimenting with anal for a while now but I've reached a point where, after a longer session with one of my larger toys, there's sometimes a little blood. Never like flowing blood just when I pass the excess lube afterwards it's comes out pink. This has happened a few times but I don't feel any lasting effects. My bowel movements afterward have been fine. Should I be worried about this? Is any blood too much or am I fine?
