A recent study found that 14-19 year olds are more susceptible to contracting genital herpes than in the past. This is thought to be due to a decrease in anti-bodies in the system, provided by better hygiene and care. It is also attributed to an increase in oral sex practices, possibly as a way to have safer sex. However, without protection, oral sex also has it's risks, including the transmission of the herpes virus.
As a doctor in the article says, "I tell patients herpes is like your credit history- whatever you did you can never get rid of". To avoid contracting or spreading HSV-2 (genital herpes) use protection for sexual activity, including oral sex. There are flavored condoms and lubricant, dental dams, and other types of condoms to fit the needs of whatever type of sexual pleasure a person is looking to try.
