In school we are often taught to remain virgins, but we are told "virgin" simply means "someone who hasn't had sex." There is a world of sexual activity before intercourse, and much of this activity is as physically and emotionally charged as intercourse itself.
We are told to remain virgins for many reasons, some factual, some mythical. One valid reason: in the heat of the moment, our desire often runs away with us. Only by having a conscious commitment to saying no can we back down effectively. Saying "yes" merely because you got too excited is bound to leave regrets.
Our bodies are designed to be sexually responsive, but we are also designed to attach emotionally to those we are involved with sexually. This is what makes sex sacred in marriage. In a "casual" relationship, this can be very bad.
Becoming sexually involved-- even just petting; it doesn't have to be intercourse-- with someone who doesn't care can be disastrous. Because some people can have meaningless sex, if sex means something to you, and now you've done it and expect commitment, but he or she doesn't, well, you can see the problem. This is why it is important to set sexual limits before you get involved. Once you are in a relationship, you are much more likely to go farther than you originally intended, unless you have a clear idea about where you stand.
If you are in a relationship, and you're personally considering sexual activity, start talking about things together. Discuss sexual activity before you do it. Insure you're both on the same page before you skip to the next chapter. Even if you've had sexual experiences in the past (good or bad), it's important to clear the waters and figure out where exactly your relationship is. Miscommunication is a huge problem.
Sexuality grows with age. It's wonderful, but don't rush it. There's a lot of pressure, but stand up to that. Many who start early regret beginning so soon, even of those who really like sex now. Nearly all who wait have no regrets. You have your whole life ahead of you; you'll have opportunities throughout to engage in as much sexual activity as you want.
Wait until you find someone you care about, and cares about you. Wait a little longer to be sure. Watching the game from the sidelines before you get on the field really helps. Sexual activity isn't necessarily "bad"-- but it definitely can be if you screw it up. Have patience. If you stand by your dreams you will acheive them.
Sex may seem commonplace, but many couples are more interested in getting to know each other than seeing what they can do to each other. Sexuality is a big part of who we are, but it doesn't have to be expressed through sex. A romantic card can share the same thought, but you won't look back on the card with regret if it doesn't last.
We all view sexuality a little differently. However, if you wish to wait for someone special, someone you truly love and enjoy the presence of, by all means, do wait, and let this serve as inspiration to you. There is someone out there.
