Rightfully like you said it. Unprotected sex is actually for married couples and it is the moral aspect of life and even religion, I believe the outcome of unprotected sex by two young person is always a path to shame and untimely death.
A friend of mine actually met this young lady who was so beautiful that every one envy her beauty so much, the guy tried eeverything to date her but she blatantly refused. After much disturbance to lady, she later decided to give him a chance of friendship. She told him they can't date. So they were close and they do everything together but the lady never allow him to have sex with her. This continued for a long time till one faithful day when my friend aactually force his way and without caution, he had sex with her despite her telling him to wait she have something important tto tell him. So after the whole thing. She opened up to him that she's HIV positive. That is actually result if unprotected sex.
