Its possible. Every relationship is different. Some men just watch, some actively participate, some like to take pics/video and some aren't allowed to be there at all during sexual encounters. I think the most common thing I experienced was a couple that had been together a while and the wife had aged much better than the husband. The husband viewed this as a way to keep her happy and to stay together. There's also a real phenomenon of guys who enjoy watching another man treat his wife like a dirty little slvt. Can't tell you how many times I was told by couples they wanted me to treat her in a manner her hubby never could, whether that meant ****, being very aggressive or whatever. I did get the feeling most of the wife's loved their husband, but didn't really enjoy the sexual aspect of their relationships with them. The usual "nice guy" thing we've all ready about on here is a real thing and a lot of married men are allowing it to ruin their sex lives.
As far as your specific question, I really never met a husband who those characteristics. Strength, vitailty and good looks are in short supply in the swinger world, especially among the men. That's why most women go with single men. If youre looking for a night of passion, why trade in your married guy for another one just like him?
