I don't get why there are some people that don't like the question you pose. It is just a question. But I do see what you mean. Yes people don't seem to wonder at all about a woman wearing diapers. It is just something like ok they wear diapers whatever.
But take for instance a guy, even a straight non-sissy guy, that likes wearing diapers or an adult baby or pacifier user and wo boy there must some reason. Why does there have to be a reason. I don't think there needs to be any reason. And it doesn't have to necessarily involve any sex component. Not that part of it can't involve sex either. But you understand my meeting, where I am going with this, right?
Well then this is also kind of like the Cross dressing thing. Women do it all the time and nobody gives that a second thought or anything lik why do they do that (dress like men). But when men Cross dressing is brought up well why or strange or automatically gay (Cross dressing can be straight). People don't think necessarily that women are gay because they Cross dressing, right?
Well same thing with diaper wearing. Or like it isn't man tough strong stuff.
But at the same time I think women are also more excepting of a man that wears diapers and same with Cross dressing.
Something funny. When I was like 5th grade watching those maxi pad I thought those where some kind of diaper because of woma older than like 13 cannot hold there bladder.
