Drive him wild: Many guys are heavily conditioned to focus solely on the genitals. "If you expand his capacity to have erotic experiences throughout his entire body, you can open up a whole other world of possibility for him," Michaels says. The thumb is actually a sexy spot for a lot of guys. "To suck on a man's thumb evokes sucking on something else, and can help him connect his mind and body during lovemaking. Start off foreplay by gazing into his eyes as you kiss his hands, and then suck on his thumb as a promise for what's to come," Michaels suggests.

Doctors used to think that human papillomavirus (HPV), the most common sexually transmitted infection in the United States, couldn’t affect the mouth. But recent research has them rethinking this notion. Scientists have now shown that the same high-risk strains of HPV that lead to cervical cancer can also be transmitted by oral sex and potentially cause head, neck, and throat cancer, as well.
