My girlfriend and I have oral sex. I heard that if you blow in the vagina of a female that it could kill her. Is that true?
Yes, it's a true but very rare occurrence. When air is blown or forced directly into a vagina — without allowing any air to escape — an air embolism (the abnormal presence of air in the cardiovascular system) could form, which can be fatal. Women who are more at risk for this unlikely possibility are those whose pelvic vessels are enlarged (meaning, increased blood supply to the vagina) due to a condition such as trauma and possibly pregnancy. So, if a very large amount of air were to be blown or forced into their vaginal canals, it's possible that the air could enter their bloodstream, causing a blockage in a blood vessel. As a result, some of these women, perhaps including the pregnant women's fetus, may experience complications. In extraordinary cases, some of these women (and the fetus) may die if the embolism travels to the heart or lungs.
If you like blowing air into your girlfriend's vulva, and if your girlfriend enjoys the sensations brought on by this, it may give you two some peace of mind to know that gently puffing some air into or breathing on a woman's vulva during oral pleasuring appears to be okay. However, it might be better to suck, kiss, lick, probe, press (with lips or fingers), or lightly nibble a woman's vulva or clitoris than blow or force air directly into her vagina. Safer and enjoyable oral sex on a woman mostly involves using a dam, finding out what feels good to her, and practice.
The answer, my friend, is not blowin' in the women.Alice!
