It is nice to find a forum free from all the abuse and spam, one sees on some others.
My names Andy, i'm 38 and live in South West England, near Bristol. I guess i'm primarily a nappy wearer, but quite interested in the whole punishment / regression thing (that is me being punished / regressed, not the other way around!).
I think my story of how I got into nappies is not dissimilar to many others. As a small child, I had probably a greater number of accidents than is usual - I think my mum was too stressed about potty training, and I was bit lazy which made a bad combination. I remember as a young child (I guess 4 or 5) being threatened with being put back into nappies - very much as a punishment for wetting / messing, although this did not actually happen. I also recall quite a few accidents in my first few years at school. Oddly though, i also remember trying on my younger brothers plastic pants over my pyjamas, probably aged about 4, so something must have started in me even back then.
Then as a teenager, I guess age 13, I found a clean disposable nappy on a path 9toddler size) that must of fallen off a pram. I took it home, very excited but of course it would not fit. This was the early 80's and with a few exceptions, the largest disposable nappies were pretty small. Ten in about '85 Peaudouce (remember them?) started making 'child size' nappies, that with a lot of stretching of plastic I could squeeze into. Also, Boots the Chemist made enormous plastic baby pants called 'Brumas pants', into which I fitted easily.
Several years and many binge-purge cycles later, I got to University and discovered in the pre-web days the 'gopher' search engine (DOS script) and realised others were out there with the same interest. Also, I discovered adult size nappies, the first of which I brought from the Glasgow Sauchihall street branch of Boots the Chemist (they were actually quite good back then).
Anyway, fast forward a few years. I am now happily semi-married (living with partner of 8 years). She knows of my interests, but has no interest herself, which is fine (though a bit of a pity!). I wear nappies etc when at home by myself. I like Tena slip maxis, the old style Kendall lille, Abriform and Molicares. But has to be plastic backed! I quite enjoy forcing myself to use the nappy, i.e. using suppositories. I've been to two nurseries (ab) but did not really enjoy the experience (and was very expensive!).
