Q: There have been two times during sex where I "queef". I don't know why and I don't know how to prevent it (its really embarrassing). Any tips?
A: Queefing (air passing out of the vagina during sex) is totally normal and is caused by air being pressed into the vagina by the penis. Some positions (such as doggystyle) tend to send more air into the vagina, because the penis pulls out of the vagina more often while having sex. If the penis pulls out completely and then reenters, it's more likely to push air into the vagina. This isn't dangerous in anyway, but, as you mentioned it can be embarrassing when the air noisily escapes the vagina. There's not much that can be done about queefing except to laugh it off. It happens to every woman. It also happens to women and men when they have anal sex, but in that case it's just called farting.
Here's a good clip about queefing from Dr. Sue, who used to have a late-night talk show about sex.
