Regarding dick size, I think that typically i'm on the larger side of the house. I've seen some pretty big ones though, i don't ask if they Penis Enlargement or not. Typically, the guys that are a little longer aren't thick at all and the ones with more thickness aren't very long. I would estimate the average size to be around 6"NBP and close to 5" around. One time, My wife was with this guy who looked pretty big but after she was with him, she came over to me and pulled me away from the two chicks i was with and asked me to fuck her right then, she said that she really disappointed with the last guy cuz he wasn't big enough to hit the right places. Another guy i recall (cuz he had a real hot fiancee), was only about 5'4" tall and about 120lbs but when the pants dropped, he looked as big as i was. It was hard to compare cuz i didn't want to stare at his dick but also cuz his small body frame may have made it look bigger.
Regarding attractive swingers... yes there are alot of hot swingers, prolly some living close to you. It just depends on the circle you hang with, the clubs/parties you frequent, and how attractive you are. We've been to places where there were nothing but skanky and shady looking people, they were mostly older and very overweight. We looked like rock stars compared to them, they all just stared almost like they were licking their chops. They were what most people typically think swingers to look like. Needless to say, we were outta there pretty quick. On the flip side, we've been to some parties where everyone looked like supermodels which can be intimidating. We felt like we were the ugly ducklings and almost felt a little out of place.
The people you see in the pics that i posted are all in their mid-30's. Some of these women have had alot of plastic surgury done, but i'm amazed how much they all workout. We also sometimes hang out with a younger group, mostly college age to late 20's people. They are real hot and wild but can be childish at times. The 30's crowd seems to have it together the most. They are usually very fit and financially stable so they can afford to go on weekend gettaways and vacations with you.
