I'm 62 and was wondering about what sex will be like as I get even older. I'm already experiencing some erectile dissatisfaction, not dysfunction. I have been doing some online research and found that despite what the pill companies advertise the majority of men still function into their 80's, just not as firm or quick. I've been reading some books about sex after 50, seems to be the magic number for authors, who seem to think it is better once the men slow down a bit. If we get that word out I'm sure the swinging community will start to pick up on it.
15 years ago as newbies, my wife and I met a guy who said the first party he and his wife attended was almost all 70 and older. The way to find partners isn't the same, but I'm sure they are out there.
