well, i have loads of nude pics of me, taken by different men, and posted on the internet. but i made the choice in doing so, because i model in my freetime (i also sat for an artist class) and they are made for my personal use, and the use of the photographer (/artist) i like them and do not regret anything i did, but i have made arrangements to get me some control over the pics.
so my tip: if you want to have pictures of you naked, for yourself, boyfriend or whoever, get a contract. a contract that specifically states the rights to the pictures, so that whenever one of the pics does turn up in the wrong place, you are in full charge and can get them deleted ASAP.
