Think you're cleverly avoiding sexually transmitted diseases by only having oral sex?
Surprise! You aren't! Not according to Details magazine's resident doctor Jake Deutsch.
Deutsch says, "There are more than 30 types of infections that can be transmitted orally," including a handful that can be passed by skin-to-skin contact.
Specifically, he points out that gonnoreah, syphilis, HPV and chlamydia can be transmitted whether you're giving OR recieving head, and that most of those diseases are asymptomatic, meaning that you could have them and be contagious without even knowing it.
You can also catch scabies or crab lice on your eyebrows and beard by giving head (even though the poor baby crab lice are going extinct because lots of people shave their underparts these days).
Lasltly, Dr. Deutsch also lays down the following fright nuggets: "80 percent of people carry the herpes simplex virus (like cold sores), the most commonly transmitted STI from oral sex; 50 percent of sexually active people have genital warts caused by the human papillomavirus (HPV), which, when orally transmitted, is thought to be a cause of head and neck cancers."
The good news? The likelihood of contracting hepatitis or HIV from a beej is very low. But even still, Dr. Deutsch says you should definitely avoid going down on anyone if you have fresh oral piercings, bleedy gums (sexy!), canker sores or recent dental surgery.
