I love wearing lingerie. I feel it adds to the whole experience. Of course I don't wear it everytime. But it's nice to wear something fun or sexy. It definitely makes me feel good.

Maybe not high enough demand. I started off kind of opposite from you: I thought a girl could be in a sports bra and still be super sexy, with the ultimate height of sexiness being when she takes everything off. I think most young guys are like this.
I changed over the course of marriage and living together when we started showering together all the time and so forth. At that point I became used to her nudity. Then lingerie started to become very exciting because I wasn't used to it, and it would accentuate her body in ways that would make me notice new things. Somehow that became sexier to me than nudity with her.
Of course with new girls it's back to just nudity being the ultimate height of sexy for me as I was before. I like lingerie mainly for LTRs as a way to break up the monotony of nudity.
