Hi OP,
I thought about your text for a long time; unfortunately I'm not sleeping very well at the moment, so I had time to think about it. Nappies, hmmm...
People with worse handicaps have found partners. I'm not saying you're doing anything wrong, just that I think you're looking too bleakly at your incontinence. You're right, it doesn't make it easier to find a partner, but it doesn't stop it.
Many problems are self-made, we often set ourselves too high standards and overlook many opportunities.
It's happened to me countless times, you're out and about, lying comfortably against a wall, drinking your beer and looking at a beautiful woman. At the same time you overlook another girl (maybe she has glasses or is a bit chubby) who is looking at you.
Then again the illusion that you have to be in a relationship to be happy: when an unhappy person goes into a relationship it is nice in the beginning but as soon as the butterflies in the stomach wear off he is unhappy again only this time someone is watching. That doesn't make it any better, believe me.
Then you arrive with your shoulders slumped, a shy look on your face and you talk quietly, get rejected and leave. Then you start thinking, am I too ugly, is it my handicap, is it my clothes, and you start to feel ashamed, but you don't realise that it was your demeanour, your lack of self-confidence, that made the difference.
