@tinyfaery: I think it’s an interesting question, and I think you’ve found something of an age/maturity line rather than a gender/sex line. People who are either older or have been in long-term committed relationships for a while, with a few exceptions, don’t seem to have a problem with it. My fella and I don’t have a problem with it. We’re in our 40s and have been together for more than a decade.
I will tell you that if I was ever with someone who didn’t want to because I was bleeding, then he wasn’t going to get any of that again. It’s a lot like a grown man not wanting to get “girl cooties”. I can do without that kind of guy.
While menstrual blood is clean it is messy and can stain. So, it’s understandable when people take precautions with towels and shower immediately afterward. I think most people above are talking “messy” and not crazy old-testament “dirty” or “unclean”.
Where the other folks are concerned, I understand where you’re coming from. But I chalk it up to “immaturity” instead of outright “misogyny”. This sort of thing can be educational for those folks. I just feel sorry for the young man who’s not going to get any the next time he tells a woman he might yak if she’s bleeding. :^> I think he will live and learn.
