Most men I know and have been with, including my husband, wouldn't do such a thing, not in a million years, and to be honest, I do not know how I would feel if I saw one of them doing it; it may be the fact that I like my men straight, not judging, it is just my preference.
Now, on the other side, I have always been very well known for being fond of cum, and a pussy dripping cum is one of those sights I can simply not resists, and most like, I would go down on her and make sure she is well-taken care.
Also, I love it if it is the other way around, and I am the one "receiving the goods" and the posterior attention from another girl.
