I was reading Four Myths About Pregnancy Sex, and this made me LOL. I'm just trying to imagine why my boyfriend would want to blow air directly into my vagina, forcefully or otherwise.
Myth 4: Oral sex is out.
Thankfully, that's not the case, and it will become a convenient option when you get too uncomfortable to have actual intercourse. Just don't let your partner blow air forcefully and directly into your vagina. Doing so could cause a life-threatening air bubble in the bloodstream.
