Re: I discovered my hubbys secret fetishes. help!
First off, you sound awesome! He is very lucky to have you as a partner, whether he knows it or not.
I think you're barking up the right tree when you say you've tried to steer things in that direction but so far, have been unsuccessful. I'd go even further and ask him things like, do you have any "off the wall" fetishes or things you'd like to try in the bedroom. At the same time reminding him that you're willing to try almost anything once, at least. Who knows, you might really like it. So, what do say big boy? I wonder if he'd come clean with you. If that doesn't work, I'd go with the other suggestion from another poster to just come out and admit you bumped into it on his computer. Honest mistake (it was, wasn't it?).
Good Luck and even though I think it's OK for married couples to keep a few things to themselves, this sounds like something that possibly both of you could enjoy. Life is just too short to not lay it out there - Go for it.
