I have slept with an ENTP with a lot of Fe but only once-I could see him looking to connect with Fe and being very confused by seeing Fi. Another younger ENTP was like drowning into someone else's body. There was no skin, no flesh, just a merging of playful puppies.
The INTP I briefly dated was interesting as I was a puzzle to be figured out. Lots of interactions quickly explored and once a path was found it was cataloged away. But precision and distinct patterns established. He was sweet...
The INTJ? My INTJ is an astrophysicist. He looks about like what you'd expect an astrophysicist to look like- a bit frumpy and kinda cutely nerdy. I have never wanted to have sex with a man this much, so much, all the time, in my entire life. We are constantly touching each other, even in a nonsexual way-almost like starving for human contact and getting the most amazing sense of satiation from that contact. He innately understands how to touch me.
Sexually, He walks in the door and I get hot. It is a slow, methodical, systematic planned exploration. This will take years (YEARS!!!!!). I find the slowness of the approach is actually reinforcing learned tactile patterns, so that the next time the same touch is made it is much more stimulating, more eagerly anticipated. He turns me into a drooling, wobbly kneed, little puddle of kittenlike lush. So much for Te, weeeeeeeeeee........... hehehe ....Yuuuummmmyyyyyyy kissesssssssss. puuuuurrrrrrrrrrrrrrrrrrrrrrr. He does this thing to my belly button.... and my belleeee and my ears......ahhhhhhhhhhhhhhhhh, hehehe........excuse me, I am dissolving into the floor now...........
(<- this very convincing smiley makes this true). what comes to entj's, well what do you expect?
