I wear women's underwear
I have worn panties since I was a boy; I'm not fifty one. The first time I wore them was when a schoolmate put a pair of his sister's panties in my gym back as a joke. But I went home and tried them on and liked the feel. I hid them and never said anything about them before I finally carefully threw them away.
While my sister lived at home, I would occasionally try on her panties. I enjoyed how they felt; they were much better than my male underwear, and I felt jealous.
I've been married for nearly 30 years and my wife doesn't know, though she occasionally have found stashes of panties I bought for myself. When confronted, I told the truth: that they're more comfortable and that I was experimenting wearing them. My kids even found out once and we had a laugh about it, but I was quietly embarrassed.
Now I wear panties most of the time, though I still haven't told my wife directly. I don't need them to have s**; it doesn't seem like a fetish. Instead, I simply feel more comfortable wearing them. I like most styles, both cotton and nylon, though I'm not much into thongs or ones that are overly tight.
