I think your instincts are telling you that what happened was a mistake. Since it cannot be undone, please just make sure you take more care the next time you consider sending pictures of yourself over the internet. I'm sure that you just got carried away, but the consequences are not worth it...and there is NEVER any reason to feel as if you have to prove yourself in this respect to anyone (i.e., to your boyfriend or your friends). Even if you started it, you may have been feeling the need to show yourself as a "free and relaxed wild child." But, as your post shows, this just isn't you...and it would be very dangerous even if it were you. So, just request that your boyfriend respect you enough to keep the images private and, better yet, to delete them from his computer. If they do get out and around school, try to keep your calm. You could simply respond with "Yes, those were supposed to be private" and try to move on to the next subject. I'm sure it will be really embarrassing, but try to play it cool...if any friends or schoolmates don't see you as vulnerable to teasing, they will likely leave you alone.
