I didn't care much about the diaper phenomena at the time in my sissy interests. Even in the porn shop's magazines, the cross dressing, sissy, & ABDL material was separate back then.
It wasn't until around 1990 in newsgroups (the usenet before the internet), & our own usenet group that I discovered ABDLs crossdressing, or sissies with diapers. So experimented a little. So it was a learned & accumulated behavior for me, that I never thought of before.
But to this day my primary interest is still the frilly old style girls clothing, tights, & girdles, or kinky women's wear. Anything that looks real extra girly. But those big puffy frilly diaper covers & plastic panties sure look & feel cool when they're well padded.
Maybe it came from the feel I had humping a nice soft pillow in a dress or tights as a kid. I didn't know how to masturbate until years later, I always humped something soft. I also always stuffed a rag or towel down the panties or tights so I didn't stain the clothing. So I had grown used to puffy pants & tights.
Another interesting thing about the boys in YCDTOTV, is that many of them had almost sissy-like longer hair. It wasn't hippie or metal rocker styled, but looked a little more girly. So even in scenes or episodes where they weren't wearing a dress, after getting used seeing them in one or some makeup, you can almost imagine them in another dress.
There wasn't much on mainstream TV that regularly showed guys in dresses, so although sometimes it would be a dozen or more episodes before they were in a dress again, it was still lot more than any other TV series. Some seasons they did it much more than in other years too.
