First thing is you need to find and wipe any copies of all of these pictures. Your husband has a real problem and even after you separate and ultimately divorce if he still has any he will be sharing them. I wouldn't be surprised in the least if he escalated to uploading them to porn sites.We have been together for 7 years and married for 6 years in the beginning when he would be the big bad biker guy it was sexy in the bedroom. But now that we have two daughters and he wants me to dress in see through and micro mini skirts in front of them I just can’t do that. I take pictures for him and him only (naked) and pics of us together then two years ago I find him on a swingers site trying to set us up and sharing my pictures with strange men. He said he was sorry and that he would quit. Of course I find it again a year later. This time he is pretending to be me and getting videos of men jacking off to my photos. When I confront him he just says that he likes the way men respond to my photos it makes him feel more like a man. I told him it makes me feel violated. He swore to me he would never do it again. Granted on there he hasn’t that I know of but now I find out he is sharing photos of me and videos and getting some in return from his friends and their wife for the past two years along with offer me up to have sex with his friend!!!!! When I confronted him he just said it’s because his friend and his friends wife are going through some things and his friend hasn’t been laid in over a year I told him I don’t care!!!!!! Of course this just happened. On another page if I don’t have sex with him daily or allow him to rub on me in my intimate parts even in front of the kids continuously then I get the guilt trips or he gets angry or the continuously jacking off 4-5 times a day. What do I do???
Your husband is a rear breed of creepy. He is addicted to these behaviors, he won't stop and will probably get worse. You might even need to get law enforcement involved. Get the pictures and do some google image searches to see if there are any publicly online already.
Get to a lawyer immediately.
