We're like you guys, long time nudists and visit our local club on a regular basis and very much enjoy the evening dances/ discos on Fridays and Saturdays. After all these years I still get the best thrills ever being there. Nearly all the woman wear sexy clothing to begin with, along with the accompanying stockings and suspenders. So horny! The men of course will normally be naked from the start. Most husbands let their wives dance with other male guests, whether married or single. I always get a buzz watching my wife dancing with other men and the fun she has with them. In the early days, my biggest problem generally was avoiding actually cumming when dancing with another female partner. Even if I only had a semi. I would get so worked up with the atmosphere and the company I was with, that usually the slightest touch on my penis, whether it was a brush against the females body or her actual hand was enough to start me off. A firm squeeze to my tip was the only cure usually. Nowadays, as you say, it's mainly precum only.
