I've met a lot of Duals, both male and female, and I get along with all of them seamlessly. I've slept with a couple of the females; the sex was very good but not the absolute greatest.* I found that the two ESIs I slept with were both selfish. Maybe that's Aggression, or bad previous partners, or maybe they didn't have their heads on straight. I don't know and I don't care. Selfishness gets you the "Try again with someone else" card.
I haven't yet met a female Dual with whom we agreed to form a long-term, sexual partnership. I have an ESI interior decorator, and we both kind of agreed (by default? By everyday repeated choices?) to have a long term relationship, but it's not sexual.
I'm still looking for an ESI who wants me as much as I want her, in the same ways, for the same reasons.
*Absolute greatest sex was with the two LSI females I dated. (They were identical in bed. Think about that when you are doubting the validity of Socionics.) Unfortunately, great sex didn't entirely make up for the rest of the relationship's qualities.
