I wear panties 24/7, almost always satin. I find the 'clingy' feeling on my backside enhanced by hot humid weather to be a continual wonderful sensation. I do wear cotton for strenuous activity, but have no similar sensual feelings in them. If GG's have a similar sensation in satin or spandex/nylon panties it might explain that serene visage so many seem to have as they go about their business.
