Whether or not you're easily grossed out, there's a high probability that you've had at least one WTF blow job experience that has somewhat turned you off. But if you're a fan of giving head, you might be willing to overlook the more unpleasant aspects of blow jobs, and for that I applaud you. Whether you're going down on a man or a woman, there are a myriad of problems that can impede your oral success. Oral sex is no exception, and can be even grosser than penetrative sex, simply because your mouth and nose are all up in someone's junk (and if you have a sensitive sense of smell, things could get ugly). Obviously, there are gross things that happen in bed in general, because the human body is honestly a strange thing, and so awkward situations are bound to arise.
For all its benefits, though, there are still a lot of gross things about giving blow jobs. Don't ask me why, but something about a warm mouth on your lady- or man-parts just feels amazing - plus, the act can be extremely intimate. Oral sex, while not everyone's cup of tea, is generally a sexual crowd-pleaser.
