Yes, I believe that sex is not a requirement. However, I do believe sex is an art. As a male with your first encounter, you will continue to think about sex 50% of the time, only because it's wonderful.
True sex requires for you to admit that you really don't know anything about the art of sex. If you would only consider sex as an art and you are the artist, always remember that the artist always makes sure that his "masterpiece" (so to speak) is protected.
Protection is needed for yourself, but you should additionally value the effects of your partner. He/she or whatever does not deserve to catch anything, especially if you are one to have multipe partners.
When you are ready to be in a steady sexual relationship, like engagement or marriage, the art will take you to a place where you have never been before.
Until such time, use protection. Remember, it only takes a lack of responsibility to catch hiv. Even if you are having unprotected intercourse for a couple of minutes and then put the condom on, you are assuming the risk.
If you are old enough to live for sex, then you are old enough to live with an hiv and all of the fears that go with it.
I'm so happy that you are taking my advise and are listening. Don't ever forget!
