Hmm. I might have something to add to this as I've come out of a relationship with an ESTP. We've had a rocky road. What has come out of dating and being with him though has been that my ideas about MBTI changed a lot.
It isn't the S and N divide in communication that was difficult. Most of his friends were Ns, and in fact INFJs. (But he has a lot of close friends that are many different MBTI types). He got along well with INFJs and he comes off as ENTP in most situations anyway. But he is definately a Se lead.
Also, the stereotype about ESTPs being unable to commit, I found untrue. He is a commitment phobe, but prolly because he takes his commitments seriously then. Once he was in a relationship with me and committed to me, he planned a future with me, practically. And he felt I was much less future-oriented and practical than him which annoyed him. (Which was true).
The biggest stumbling block for me seemed to be the very nature of Se and Ni in us. He follows his instincts in the present, I follow my gut and plan ahead based on past information. And I could never feel completely and totally secure in the relationship because I sensed how he perceived the world ; as things happen in the real world. I rely more on my intuition and less on the real-world experience (although obv we both do both, as well). I just didn't get a very comfortable, safe feeling to totally let my guards down. It was also how open-minded he is and how friggin P he is. He keeps options open in many ways and isn't very straight-forward at all about his feelings and thoughts. (Aka there's so much more going on inside of him than comes out, and he works on several planes simultaneously - so I never get quite the read of him, which also annoyed him).
He felt annoyed about me being too closed off and basically not what he wanted out of a girlfriend. I wasn't practical enough, confident enough, athletic enough nor as socially capable as he would've wanted me to be. But those are the little things, the big thing for him was that I wasn't able to get a proper read of him, he understands people so well and me and my motivations scarily well, but I could never return that to him. (Well he is a very complicated person)
The good stuff: the sheer physical chemistry and the love. We love each other like mad and when we're in each others physical proximity we just feel really comfortable around each other. I love how playful he is and how grounded he is and how silly he is. I love sharing experiences with him. He likes my sillyness and niceness. He makes me pay attention to things I wouldn't otherwise and makes me experience things I otherwise wouldn't because I don't honestly naturally pay as much attention to these things (the best foods, hands down. The best gigs.) He helps me be more relaxed in situations where I'd otherwise feel really tired. But somehow being around him in eg crowded noisy places don't stress me at all.
There are definately good things and bad things. We're no longer together. But what can I say about this specific guy who is ESTP.. He's very loyal despite what I wrote about my insecurity with his obvious Se, and he's otherwise very don't-give-a-flying-fuck-if-you-jump-off-the-bridge kind of a guy but if he loves someone, there's not much I've honestly seen that could compete with that in terms of compromise and caring.
He is a lovely person whom I don't want to live without in my life... We both make each other happy. We just love each other, even if we can't make it work in a relationship.
