I was and still am in the same situation as you.
I have 2 children and a wife.
They know nothing about this side of me. And I cannot share this with my wife.
It is hard not telling her but if she new I do not know what would happen.
I have been wearing diapers for 5 years now. On and off.
You may go though the binge purge cycle like most of us.
I just accepted this is the way I am and am fine with it.
But I must say I still wonder why I like wearing diapers etc so much.
Anyway go for it I say you only live once.
