as a male i don't mind. sometimes when getting head i will give my lover a break and pull them up closely to me and deeply kiss them. then let them resume the blowjob. would not have a problem kissing someone with cum on their lips after i came in their mouth
I'm guessing that oral on her after sex would kind of freak some of these folks out. I think when I was 16 and stole one of my dad's playboys, I read a statement that said that if you're man enough to make the mess, you shouldn't have any problem with cleaning up. Kissing a woman after head is sexy; it says that what she had been doing isn't gross, and that everything involved in the lovemaking is beautiful.
