I've meet a few ESFP women in my time that I was very interested in. All of them however were either married or dating some other dude at the time, so no go for it. A shame too, we got along very well and they were quite delightful to be around

I think we go together REALLY well! I dated a gal who tested ESXP. In retrospect, she told me that she admired me and respected me for the things I did for her, like making sure she was safe and happy. That means a lot to an alpha ISTJ.
One of my friends is ISFJ and another is ESFP. They are also good friends of each other. The ESFP comes to talk about her problems to ISFJ because she knows that ISFJ girl will never tell anyone else. ISFJ is very trustworthy so ESFP approaches her as her confidante. At the same time ESFP girl brings spontaneity into the friendship so it works very well when they are left alone or in a small group, but at parties in a crowd of people they are much more distant.
Besides that, I haven't found a single ISTJ-ESFP couple yet. The ESFPs I find are always with other types, mainly feelers, and ISFJs in particular. I'll tell you what I like and what I don't like about ESFPs....
What I like: ESFPs are very generous people to everyone around them. They give, give, and give freely without any expectations of return. They are warm, kind, friendly, and very accepting people. They are laid-back, casual and down-to-earth so everyone feels very comfortable around them. They are fun to hang around and playful! Most ESFPs are sensual; they are physically attractive and they know how to make themselves look hot.
What bothers me: Sorry if this offends any of you, but some of the things that come out of your mouth are just ajkdlfkjasieworildf. You guys live entirely in the moment, so this is difficult for you. You need to think before you say some things. You may have offended someone without even knowing it. [I can catch it and I'm a thinker???] Or just saying something stupid can be a turn-off for ISTJs.
