Is oral sex really sex?

Yes, it is!

Many teens believe that oral sex is not sex because sexual intercourse is not involved, and thus it doesn't fit their definition of “sex”. The purpose of sexual intercourse is to create new life and bond you and your spouse. Oral sex does neither. Sadly too many teens are unaware that risky sexual behavior, such as oral sex, can transmit life—threatening and incurable deseases, such as HIV, HPV, genital herpes, chlamydia, syphillis, and gonorrhea.
