Can I include my partner in this? His best trait, as far as I'm concerned, is that he can live with me. Not an easy task, cause I'm not an easy person to get along with.
Especially since I always gravitate to being in charge, it just happens subconsciously, and I'll trample right over a guy who can't stand up to me, who can't tell me to go f*** myself. My most successful BFs and partners have been as strong-willed as me, and yet tolerant & patient with me. My worst match is a meek guy, who can't say no to me.
Aside from that, he's gotta like my warped sense of humor, and be able to act like an immature kid with me from time-to-time, with his own humorous talents. My present partner can do all that, and more.
And guess how I know I've found the right guy? When gays we don't know tell us they assumed we've been together for many years, and are incredulous that's it's only been a few months. That's when I know we've both gotten our mutual mix of traits correct, and we have some potential for a longer relationship.
