My girlfriend and I were dating for a few months when one night in late December we were up late getting drunk, and I told her about my diaper fetish. I explained where it came from and why, and she was okay with it. She told me that it wasn't the most strange thing she'd ever heard of, just that she didn't share that interest. She told me that if I wanted to wear diapers, she was cool with it, and if I wanted her to occasionally wear one, that was fine too. I had been dying to get that off my chest, and I explained that to her. I asked, "would you rather have had me tell you now, when we've only been dating for a few months, or would you rather have had me tell you when we've been dating over a year?" She is the ONLY other real-life person that knows about my fetish. After 15 months, we are still together in a very loving relationship. I love her with all my heart, and I'm 100% sure she feels the same. If you want to get your girlfriend into diapers, I'm not an expert by ANY means. I only know what worked for MY girlfriend. First, pray she has an open mind, and isn't very judgmental. Second, make sure she's in a good mood (and I wholeheartedly recommend you both get drunk at home). It makes any confession easier; both to give and to take. Third, be ready to explain where your feelings for diapers originates. Fourth, make it clear that you told her because you know you can trust her with your secret. Where you go from there depends on her reaction. But if your girlfriend keeps an open mind, and you let her know that she's #1, not the diapers, you just might be able to get her blessing and participation. I hope this helps.
