This is an interesting question. You'vre got me thinking. Uh-oh!

There
are a few things that don't mix with my diaper-habits and that's the easy answer, but then I wonder
why they don't mix and that's a tougher question to answer.
If a person were incontinent and required nappies for a genuine medical reason, I would imagine that all areas of life would mix more easily on a psychological level. Sure there might be some things on a physical level that are impossible or difficult in a diaper, like wearing a bikini. (ok, I can't think of an example!) And I'm sure some circumstances might feel odd at first. But on the level I think this question is getting at, you'd probably feel ok about it. And it might be easier to explain if people found out you were wearing.
If your reason to wear is nearly completely sexual, then it might feel weird to mix nappy-habits with things you wouldn't associate with the sexual element of who you are.
If you wear for emotional boldness and comfort, the situations that 'mix' might be a little a bit more varied, depending on who you are and how you experience the various aspects of your life.
So...to actually answer the question now...
I partly agree that it doesn't quite mix with 'matters of faith and God' for me. But, having said that, I have found the use of nappies to be strangely 'healing' or maybe words like resolving or reconciling might explain it better. Past hurts from young childhood and issues of shame and fear have progressed towards a healthy balance since I at long last indulged this 'need'. I'm undecided about whether my recreational diaper-wearing really can go together with my faith but I'm open-minded about it until I decide what I think.
I don't wear while with my fiance.
I don't wear if I am going to be around children. (Not least, if they notice, they'd yell it out! But also it would confuse them which isn't fair and it might give a wrong impression.)
