Oral sex is not safe sex

A study indicates that oral sex with one to five partners in a lifetime doubles your risk of throat cancer, and oral sex with six or more partners triples your risk. To get the same risk elevation through vaginal sex, you'd need many more partners. Transmission vehicle: HPV. Other risk factors: infrequent use of condoms, poor dentition, infrequent toothbrushing, and heavy tobacco use. Boys, let's hope the women haven't got wind of this.
