No, many times INF men feel to me, inside and metaphorically, like little children clinging to my skirts, it's not sexy, it makes me think of my little brother or being with another girl.
I think I'm shamelessly attracted to a certain ideal of masculinity - not big and physically imposing masculine - but rational, orderly, in control masculine. It's almost like I have to look slightly up to the guy I'm with for whatever reason, like I'm slightly submissive despite my bratty behavior, and I desperately need someone calmer and more practical to balance me.
I was raised by a very overbearing ISTJ who, in turns, spoiled me rotten by petting me and buying me everthing, and then later terrorized me with discipline and control.
Might have something to do with it.
You'll have to ask other NFs why they're attracted to what they're attracted to. It's an individual thing, though you may notice some trends.
