Situation:
My friend and her boyfriend have been going out for the past year now and they just recently became sexually involved. He has a really high sex drive and she likes to think up random things for them to do to keep things 'spicy'. Last week she confided in me that they sometimes did it even while she was menstruating and lately they developed a taste for a practice called 'red-rosing', where she told me that her boyfriend basically goes down on her when she is on. They are both really careful and he doesn't drink it or anything (spits it out or just pleasures around the area)
because she says she is more receptive to pleasure then.
Now although it is not my place to criticize her relationship, but I can't help but think that these acts are a little bit weird and somewhat disgusting. I don't want to seem like a prude but when I first heard of the term I thought it was gross. They both practise safe sex, always using condoms, contraceptives and the like, but it still made me sick just hearing about it. I think it is risking and at first I thought it was an urban myth, but apparently it is well known, especially with couples who include oral intercourse within the usual intercourse.
Am I right to think the practice is disgusting and risky? My friend's boyfriend is a nice guy and I know that both she and he would never take any risks with their sexual health but I am still just grossed out about the whole thing. What should I do?
Guys, do you do the 'red-rose thing' with your girlfriends or does the thought disgust you?
