I know that the majority of people use condoms and birth control and whatnot. However, I've found that the ratio of women whom use condoms while performing oral sex on a man is a lot less. Also, and hell I didn't even know this one until I read it in a book.....Some men use things called dental dams or they cut an unlubricated condom into a square piece and use it as a barrier between the mouth and the vagina. Hell, some even use Saran wrap? Do any of you folks do this? Do you use protection during oral sex as well as penetration?
