Part of my fetish is the shopping and buying of diapers. I can't wait until I get my order. And when they arrive I get way horny. Just knowing they are sitting on my porch. When I buy in public I always go in wearing one and pick the cashier that will be the most embarrassed by them on his or her register.
No reason to quit. It's harmless and fun...and my wife likes it (including watersports) so it's a win-win. I also collect various cloth pull-ups, incontinence briefs and trainers. Trainers are my daily underwear as well.
Cheers.
