For me, discomfort with nudity as lee would have to do with feeling ashamed or self-conscious about certain areas of my body, and not wanting them to be seen, feeling that they look unattractive exposed. My lower stomach in particular is one of these spots. I'd guess a lot of ladies who have had babies might feel the same about this same area. I feel less sexy than when it's covered. To be tickled nude would definitely take time, trust, and a play partner I had grown very comfortable with physically. I've felt very sexy, and like the clothing didn't reduce the erotic appeal of feeling vulnerable, exposed, or reduce any ticklishness, when I was lee wearing a chemise/short sleeveless dress, or high-waisted skirt, or just bra/panties or nylons w panties. For things to get more sexual, the short dress/skirt worked best to allow that without exposing my belly & feeling self-conscious about it. Also guys for me at least, I do appreciate the thought & caring behind it if you do this for your woman who might feel similar... But saying "It looks fine, it doesn't look bad to me, it's cute, I don't care if you have (stretch marks, flab, loose skin etc), it's fine!". That doesn't really help. I'm glad that guys will be kind in this way, but you can say how totally not bothered with the way it looks all day long. I'm bothered by how it looks. Unless we're very intimate and close, my whole belly being exposed/being totally nude will put that insecurity about having it uncovered and in full view into my head, where it will take away from my enjoyment of the experience as lee; take away from being able to lose myself in the feelings the ler gives me tickling.
For me as ler... Honestly it's about the comfort level of the guy. If he wants to go nude, more power to him. If he'd rather keep anything covered... I will understand, and I'm aware some of the guys might be just as self-conscious about their belly and want to wear a tshirt/tank to keep it hidden too. I totally understand that. I think I could still enjoy tickling them just as much clothed or unclothed. Also, lol damn, even if they're gonna come off at some point in a session ... If a guy is hard while I'm tickling him, and still wearing boxers, briefs or boxer-briefs, it is really really hot to tease him for a while thru the fabric, before pulling them off 😁 I'd miss that with a nude lee guy maybe a little, haha.
