Wife and I have been married 6 years. She claims she has no sexual fantasies but I have my own. I haven’t had the courage to bring them up to her because I don’t want it to adversely affect our relationship and I don’t want her to have a ruined image of me in her mind.

Some context: we are good church members but we have fun and don’t tell anyone. She knows that I like her dressing slutty in public sometimes. We will take trips to Vegas and we go to topless pools and sexy adult night time shows. She knows I love showing her off and she likes it as well. At the pools she wears a g-string bikini for her entire butt to be on display, and out on the town she wears really short skirts with no bra and a very revealing top. It is a goal of ours to make it to some nude beaches in the Caribbean this coming year.

My fantasy that I haven’t shared with her yet is that I fantasize about her with other men. I also fantasize about having her with another man, an MFM threesome. Now, obviously that most likely isn’t going to happen and I’m totally fine with that, it is just a fantasy after all; but part of me wonders if she would use it in dirty talk when we are in bed or as something to bring up to tease me with occasionally. I just get worried about admitting it to her.

I guess my question is, has anyone brought up a fantasy to your significant other whether it is related or not and it had an adverse reaction on your relationship? If so what was the fantasy? What was the negative affect? How long did it last? How did you get over it? How can I bring up my fantasies to her and how can I gain the courage to do so and get it off my chest?
