Umm, well the idea is that I was walking home with a guy one evening, ....
Well that's an awful experience, I can well understand you not wanting to repeat it.
I live in a very rough neighbourhood and although I'm no great fighter and I'm not particularly physically strong, I've managed to escape quite a few controntations unscathed, but every time it's been because I sensed the intent before they got within reach of me, and took the initiative by opening verbal negotiations, so to speak. Every situation has gone from an extremely tense beginning where anything could happen, to ending with them sharing cigarettes with me and we've patted each other on the back like old pals before parting.
So whilst I couldn't necessarily say which type would be physically able to protect you (maybe ESTP is odds on to have the athletic ability and strength, but that doesn't guaruntee that they have the courage when in the line of fire), I can say that an ENxP would be likely to diffuse most situations from happening in the first place.
Oh, and incidentally, I'm violently, hideously jealous. I mean really... seriously. I do my best to restrain it and not be possessive, but it's hard... and weird too, cos with friends I'm completely laissez-faire. It's just when romantically involved with someone, I'm quite ENTJ-ish in expecting total, unswerving loyalty. My partner is the sun to me, and at the first sign that I'm not to them, I'm outta there. Which is why it's been a good thing I've been celibate for years and am staying so from henceforth!
