You are responsible for your body. Decide what you want out of life. Do you want many brief, anonymous sexual encounters? Do you value physical activity more than emotional commitment? Or, in your opinion, does emotional involvement come first, and physical satisfaction second?
Generally, people who wait for long-term (year-plus), loving relationships have the most positive sexual experiences, if indeed they choose to have sex, which many don't. Some couples enjoy just being together, and kissing, but see little need to go farther. Why should they? If you're romantically inclined, a massage is a much better gift than a blowjob.
Whether you want a serious, committed relationship or a series of flings, don't engage in sexual activity because you don't think you'll find someone who loves you. You will: the majority of people don't marry until well into their twenties, and many of these men and women never dated in high school, much less junior high. There's someone out there going through the same thing you are. You will meet this person; the choice is whether it's worth the wait. Choose what makes you comfortable. Do not compromise your beliefs, regardless of what others think. You have to live with yourself afterwards. Others don't.
Oral sex is a good example. Some girls think they can give head to "keep" their boyfriends while still remaining "virgins." First, any guy you must give sexual favors to "keep" is not a guy you want to be dating. Secondly, isn't oral sex sex? Oral sex puts you at risk for STDs just like "normal" sex. Sure, you won't get pregnant, but you might be prevented from ever getting pregnant (many STDs can cause sterility).
Oral sex isn't just physically risky; you put yourself in emotional jeopardy as well. Think: you're putting your (or his) penis in your mouth; few things are more intmate than that. You really need to trust your partner. NEVER get involved with someone who doesn't treat you right.
If you limit virginity to meaning "never having had sexual intercourse," I suppose you can still be a virgin and have oral sex. But that's missing the point: oral sex is heavy stuff. Some feel oral sex to be even more intimate than intercourse! You have to reject the idea "virginity" means "going as far as possible as fast as possible without penetration." Not only is this view physically and emotionally dangerous, it's wrong.
