You would think that because there is pleasure in sexual activity that sexually active teens would be happier. That is not the case. Unfortunately, there is a strong association between sexually active teens and poor emotional health.
Sexually active teens are more than twice as likely as virgin teens to be depressed and/or attempt suicide. Teens report that they had less self esteem after becoming sexually active, and a lot more regret.
Also, sexually experienced teens, especially girls are much more likely to experience dating violence, sexual abuse, and unwanted or forced intercourse than their virgin peers.
