"How to approach him?" You're allowed to say "no." You have your own life, and your own feet. Walk away, if he asks you to do something you don't care to do. Seriously.
"but he hardly listens" ,Then stop undressing and stop having sex with him. It's that simple. He will listen then.
Unfortunately, he may try to blackmail you with them in the future some time - how many pictures does he have? you have to get him to prove that he had deleted them and then bail on than guy; sounds like a bad scene
i agree with you all,but how to approach him,i have been asking him not do such activity in past but he hardly listens
If you aren't comfortable with it, why agree to it? I agree with Annie, it's a dangerous, dangerous thing to do, especially in this day and age where everything (well, almost) is going on the Internet.
He is obviously getting his kicks from it, but since u aren't, I would demand to put an end to it, and (if possible) retrieve your pictures, and tell him you don't approve if your pictures popping up somewhere in the future.
is it a fetish? a fetish is when you cannot reach orgasm without it? as long as you are comfortable with it.... i suggest asking him.
Either:
- he's a photo fetishist
- he gets kinky pleasure from thinking other people can see you
- he's a sexual control freak
- he's selling your image online
Take your pick, these aren't good things unless you are also an exhibitionist. You sound like you're rather passive about it, I'd take a firmer hand over the future of nude pictures of yourself.
