I have liked diapers all my life. I discovered it when I was about six years old when I saw some plastic snap on pants at a neighbour girlfriend's house. It made my heart pound and I asked her If I could borrow the plastic pants for putting them on my stuffed animals to play with. The same night I put the plastic pants on myself when I was in the bath tub. Some years later I found old pampers in a closet at other neighbours. I took two out of the box and put them under my shirt and went home. I used them (not wetting them or anything) for the next years, until they fell apart. At the age of 7 or so, I used to make diapers from plastic bags and towels, which made me feel good.
Nowadays I wear a diaper whenever I feel like it. My girlfriend knows about it and has no problem with it. She even asks me sometimes before going to bed, if I would like to put one on. I think that's great.
Before being with my girlfriend I have dated with another diaper lover, just to experiment. I did feel good at the time, but I wouldn't do this anymore, since I am in a relationship now.
