You'd be better off knocking up a couples profile for you both and getting it verified as otherwise to everyone you will only ever be a single guy with a single guys profile.
Yes you have better experience on couple profile. Personally, I just attend swinging clubs first and use this as a secondary place to keep in touch or meet more couples.
I'm with everyone else, you need a couples profile no one ever believes a single men's profile is part of a couple.
Get some pics of you together and get started.
Good luck.
