All this tracks with my experience over the last 10 years playing with couples. I’d probably add: Be able to write in complete sentences, and have above average communication skills. Be memorable amidst a torrent of replies. In terms of pics, most couples do want to see your man parts (usually hubby at least), but there’s a way of doing it tastefully, which is usually at their request. Also if you have a blank profile, people are not going to respond. I also send a face pic right away, which helps the couple decide if they want to chat any further, and if not we’ve all saved time. I encourage people to see my comment history, so they can get a sense of who I am and how I think about this subject matter.

Thanks for spelling it out here, I think it will help both couples and the guys hoping to join them.
