Personally, considering the number and nature of “racy photos” of people from all walks of life, all age and economic groups, and nearly all cultures abounding on the Internet… I wouldn’t give this a second thought. Yeah, when those photos come to light online it could be somewhat embarrassing for some period of time, but you’ll get over it.
If you gave him the photos and now you’re having second thoughts, then it’ll be a good lesson to you to:
1. Not take photos of yourself in those positions or allow others to, and
2. Use better judgment on who you give such photos to.
Since @MrItty is absolutely correct that you have zero control of this issue any more, you may as well admit that “I no longer have control of this issue” and change your mind about how important it is. Otherwise it’s going to eat you up.
