“I talk about this with patients almost every day in my practice,” says Mary Rosser, MD, assistant professor of obstetrics and gynecology at Columbia University Medical College. “Of course, I’m usually the one who’s bringing it up. Not many women want to or think to ask about it.” That may be because oral sex still has kind of a risque reputation to it, even though it's a pretty standard part of a typical couple's sexual repertoire.
People give various reasons for their dislike of oral sex. Some state that since it does not result in reproduction, it is therefore unnatural. Others find it less intimate because it is not a face-to-face practice, or believe that it is a humiliating or unclean practice; that it is humiliating or unclean are opinions that are, at least in some cases, connected with the symbolism attached to different parts of the body. Opposite these views, people also believe that oral sex "is one of the most intimate behaviors that a couple can engage in because it requires total trust and vulnerability."
17. You can use your tongue to trick him into thinking he's all the way in your mouth. Like ~magic~ if magic were perverted and used only to trick men into thinking you give the best blow jobs in the world. You don't have to just tuck your tongue away and hide it while this event is taking place. You can use it (like the roof of your mouth thing) to trick him into thinking he's basically pumping away into your stomach. Just either tuck his penis underneath your tongue, or use your tongue to block the back of your throat (this also protects your delicate gag reflexes just in case).
Really, this happens. In a recent BMJ case report, dentists detailed how a patient who regularly performed oral sex on men developed a strange lesion on the roof of his mouth, due to “blunt trauma” during fellatio. The sucking motion associated with fellatio may have also played a role, the authors wrote, causing blood to pool and clot in this area.
