I recently witnessed a heated argument between my friend (I think he may be an ISTj) and his girlfriend where he jealously exclaimed "I know how guys think. The only reason your guy friends want to hang out with you is to get in your pants!" It was said in such a matter-of-fact way that I believe he sees no value in non-romantic female friends. What strikes me as weird is that I can see how he can think this way (and find it hard not to think that way myself) and am wondering if this has anything to do with "Logic of the Relations"
Am I completely off?
