Funny period sex stories

One of the first few times I had period sex I went to my boyfriends and we were getting it on and everything was great until I get off from on top of him and a blood clot falls onto his thigh and he had no idea that girls get blood clots during thier period so he starts saying "oh my God are you ok something bad just fell out of you! " I said no its just a blood clot and he was like "OH MY GOD GET IT OFF " it was hilarious and we couldn't stop laughing. Love that man. Whats some funny period sex stories you have?
