I mean, it is what it is. In the bigger scheme of things, it's pretty much neither here nor there.
The theoretical willingness is the more important factor here, because you never know what life is gna throw at you. One of my brothers got hit on his motorcycle by a hit-and-run driver, and smashed both arms, and his girlfriend had to wipe his butt every time he went number two for about 4-5 months.
I have dated a women who was wearing diapers and rubber pants.. I only found this out later.. on the date.. she told me the first night we went out.. and said that the reason she did not tell me sooner was that she just could not find the words at the time and because she and I hit it off pretty good from the start she did not want to say because she figured it would drive me away.. but she was so very wrong on that account.. because I happen to wear diapers and rubber pants same as her., for a medical need
I have went with many women that have excepted that I wear them.. and for sure I will except the any women that also wears them.. wearing diapers on a date to me is by no means a deal breaker.. what comes around.. goes around.. this I no does not address the question you asked.. but it was a on the same lines.
Honestly I don't understand the wanting to change/baby you with the diaper. If you're into that then thats great but its definitely not something I would want to participate in. I like men so I want a man not a baby when I'm dating.
Otherwise, the diaper thing wouldn't bother me. You can't help that you're not incontinent and it doesn't change who you are as a person.
Its no different than women having to wear hygienic products while menstruating. Its just a part of your life now. A woman that wouldn't want to be with you just because you have to wear briefs, isn't a woman you want to waste your time on.
