You are 16, and have many issues that needs to be solved, so to have a healthy relationship, don't give it up at all. Then the horndogs will leave you alone, and you can meet a better class of guys who are not just users. Plus you can get your lust under control, and enjoy you youth while you have it.
Life and love are more than just sex, or having a guy to use for steady, repeated sex. You want a relationship? A good one, then you have to put building one first, by taking sex out of the equation all together. Then you will know a guys mind, and he will know yours. Stop thinking like a guy who doesn't care about anything but getting laid, by who ever is available, and think like a girl who wants real love, and romance.
Learn respect for yourself, and others will respect you for more than just a body, and make love to your mind. Then the waiting will be worth it for a good guy, and not a reward for some horndog. Or you will always be in the use, and be used crowd. And you will never know what a healthy relationship is if you keep reducing yourself to the female version of the dogs you deal with now.
