Have you openly talked about your fetish with your wife?  Have you ever taken the time to ask her about her "unconventional" interests?  This issue comes up a lot on this site, and as several have observed above, the only real question is whether you broach the topic at a time and place of your choosing, or have it explode in your face when you aren't prepared to deal with it.  Marriages become hollow shells once trust is lost, and there are few things that will end trust quite as spectacularly as lying to your partner about something that goes this deep into your personality.  

I let my wife find them when I left them out “accidentally on purpose” because I was too chicken to just bring it up. It started a discussion and here we are today years later. 

15: Gasoline   Zoey came out of her memory lapse and blinked to Dr. Mastermind in confusion, “That was… real?” She asked, feeling so disgusted of things she never knew almost happened with Dogman Jones and Captain Thwart. They were thirty years older than her and disgusting old men! “Yes.” He said, a flicker of regret in his eyes to show her that, “I didn’t want you to remember that, but this conversation left me with no choice.”  Zoey shook her head, “I just… this is a lot to unpack.” She shook her head, putting her hands through her long dark brown hair. “We can use your session today to talk, if you’d like.” He said, watching her carefully, eyes flicking over her fingers threading through her beautiful dark brown waves. “I mean… I just don’t get why me saying that lead you to make me like diapers? That’s what I can’t unpack the most.” She shook her head. Looking into his warm brown eyes that flickered humorously. “Because you didn’t know how much you liked diapers until I introduced you to them.” He said, tilting his head as if it were a known thing, “Against popular beliefs, I can’t entrance someone to like something they hate or are disgusted by in the longterm. I can only coax and show what it could be like.” Zoey shook her head, “But that doesn’t help explain why I org-“ She hesitated to say the word, “orgasm every morning?” Dr. Mastermind smiled playfully, “I thought that would be nice, is it not? I can make the wet dreams stop if you insist.” “No-“ She scrunched her face, saying no so quickly, “I mean, they are nice.” She said with a frown as Dr. Mastermind gave a knowing smile to her. “I just don’t get why you do this… with every patient right, not just me?” She asked, wondering if Joey, Trident and Ivy were the same. He chuckled loudly with a shake of his head, “No, I don’t. Haven’t ever crossed that line with anyone else.” He calmed down and settled back in his chair with a ghost of a smile.  Zoey frowned, more confused, “Then why me? Why diapers and everything else?” His eyes switched to a lustful look suddenly, “Because the day I met you I couldn’t stop thinking of you being my little baby and exploring what that looked like to have you under my control.” Zoey felt warmth in her chest down to her lower abdomen from his words. It made her hot and bothered as he looked at her and she knew he knew how she felt.  “I-I just don’t get it. I don’t get how you asked me about my deepest desires and that turned into diapers, embarrassment and being babied still.” She said, trying to pull out of him that it couldn’t just be her who liked the babying and diapers. Dr. Mastermind blinked with a humored expression placed on his face, “I’ve always had a…” He trailed off, looking to Zoey’s crotch, “fetish, one could say, for control and humiliation in it’s rawest form. Diapers, wetting, other things are just in that spectrum that gives me total control. Finding someone who’s consensual and willing to do those things is rare.” He said, licking his lips as he looked into Zoey’s eyes. “Finding someone who I’m attracted to mentally and physically is even rarer.” Zoey bit her lip, “So that’s how I’ve been turned into this,” She waved to her padded crotch, “from your own deep desires?” A bit of hurt was in her eyes now. Although his words validated her thoughts that had been cycling in her head for so long, she couldn't get past the diapers. He shook his head, “Don’t get yourself confused, little Zoey. It was a part of yours too, I just had to show you what it could be, and you liked it, more than you and I even knew possible.” “How can you tell if you’re just brainwashing me every session?” She said, not believing him fully that stung Dr. Mastermind’s heart. “The sessions weren’t me brainwashing you, that’s a negative connotation I don’t like to use for what I do.” He said quickly, annoyed from her continued usage of the word, “I hypnotized you to a deep trance-like state between your unconscious and conscious self to learn who you were in your rawest form. I helped that come out that you were experiencing heightened excitement like you’re feeling now. That’s normal." He paused, eyes serious and unwavering to Zoey as she blushed at the idea that it wasn't just Dr. Mastermind brainwashing her. The realization hitting that this weird new diaper-lover-thing and being babied was something she actually enjoyed too, "The wetting and other things I hypnotized are another story, something I thought would be fun with you that’d you enjoy, like the wet dreams.”  She blinked to her hands, studying her tiny fingertips in a sadness of realizing that the past few weeks she was in a hypnotized state, “So, how do I know what’s real or not? How do I know I really like this if I’m hypnotized to feel these things?”  Dr. Mastermind took a deep breath and crossed his arms, “I’ll stop everything and let it all fade. It’ll take a week, in which you’ll be leaving by then.”  Zoey looked up to his eyes, her eyes suddenly sad, “What if I don’t want that?” A corner of his mouth went up, “What do you not want, Zoey?” He leaned forward, intrigued. “If you can read my mind, why do you still ask me questions?” Zoey asked, crossing her arms. “Because I like seeing you squirm and blush when you answer.” He said, playfulness shadowing his eyes. Zoey giggled softly, “I don’t want to leave nor stop. I want to be…” She blushed, knowing she just gave him what he liked, but, deep down, also what she equally craved for, “babied and diapered. I want the full experience before I leave.” She said, swallowing and maybe not knowing fully what that meant yet. He got the pocket watch out of his drawer and tossed it to her, “Then let’s begin our session.” 

Met in person or met online?  Because if online this sounds like the start of a blackmail scam.
