Get to know people. Go to meets. Visit with others online / irl. Use fetlife, telegram, etc. You'll find people in your area, and in time, get a change or changing them will happen.This is something i have wanted to do my whole life and still have yet to do it
I've changed a fair few ABDL diapers and it was not what I would call hard work. I'm not Mr. Universe by any stretch, either. Smaller people are easier but a lot of what I've changed have been large/XL.About 20 years ago, like you, I wanted to see what it was like to have someone, a real person, change my diaper. I tried the "find a mommy" route and then I tried the "pay for play" route with paying an escort to do it. Both ways were less than I had hoped for or dreamed of.
The "Mommies" I found through personal ads were not really "mommies" at all but lonely middle-aged women who would do or say anything to be in a relationship with a man. I had to constantly give them "direction" because they were simply not "into it" and in the end, neither was I.
Then I began hiring escorts and I got the same results, only now I had to pay for it. Again, the escorts, like the "mommies" I met, were just not into the ABDL lifestyle. In the end, I just gave up and realized that I do better with just me and my fantasy. Although, at least I did get to experience another adult diapering me, but to be honest, diapering a 200 pound man verses a 20 pound baby, is two entirely different things. Ask anyone who works in a nursing home and they will tell you that it is VERY HARD WORK to diaper another adult. The back injury rate is off the charts in nursing home employees.
Anyway, that was my experience being diapered by an adult.
I hope this was helpful.
