The best way to interact with me (one ENTP, so I'm not necessarily generalizing here):
1) Don't bullshit me. Just because I'm not an inherent Feeler doesn't mean I can't sense the vibe in a given social situation or how someone else's mood or attitudes are shifting in accordance with their interaction with me. I'm usually very good at telling whether or not someone is humoring me or genuinely interested in my company and conversation. If someone is laying on the bullshit without being transparent (meaning, if we're not both in on a joke) I will become defensive and suspicious of motives. For instance, I hate it when someone patronizes me by agreeing with something I've said merely in order to avoid an argument or to ingratiate him/herself with me, and I can almost always tell when that's the case (face-to-face; internet forums are a different matter).
2) The Place of Argument: many people have picked up on how ENTP's like to argue. Well, there are many caveats here. I enjoy arguments as long as the opposition doesn't get shrill or launch into ad hominems. This might, in fact, be an appropriate time to gesture towards the important difference between an argument and a debate, where I'm provisionally defining "argument" as debate injected with vitriol and a loss of emotional control. So I prefer to debate. That doesn't mean the debate can't be passionate, but I'd rather not have to deal with someone who's quivering with rage at my presumption or butting in every two seconds to argue a half-uttered point. I'm more than happy to admit I'm wrong or, at the very least, concede that I've got a long way to go to providing defeaters for certain points someone has made, as long as the good humor of the situation is not lost. In this ideal sort of debate (I've had many, thankfully), I am able to gauge a lot about a person, his/her ideals, his/her spirit, his/her cogency and coherence of thought, his/her passions. Debate is, ultimately, my favorite way of getting to know someone.
So, 1+2 = 3) Therefore, if you Don't Bullshit me and are able to have a decent argument (viz. debate), I will like you even if you don't agree with me! A healthy respect can evolve from a deftly-danced debating session. I'd rather be respected for losing a hard-won debate than given the impression of respect because someone lay supine to my less-than well-formed arguments.
____________________________________________
In general, I won't appreciate someone instantaneously getting in my face as a challenge. I don't typically do that to other people. I let the relationship progress a few stages beyond the handshake, such as indulging in the pleasantries of getting to know where the other person is from, where they went to school, what's his/her favorite book, what he/she thinks about the role of career in defining one's personality/personhood.
Physicality: even with attractive women, I'm not big into physicality early on in a relationship, whether Platonic or not. I have to decide that I like you. Having someone I'm not decided on embrace me on our fourth meet-up is having my personal space invaded. Allow the dynamics of the relationship to reveal whether or not I'm ready for that. For me, around the same time that I feel like spontaneously calling someone up for a phone chat (and not merely to organize a coffee date) is when I'm ready to start hugging or doling out kisses on the cheek.
