Some brief thoughts... I find that Fe-Doms are more intrusive than Fe-users.
Having an EXFJ hug you, wanting attention, demanding you love them.... it's all very exhausting after awhile.
Having a Fe-user hug you, wanting attention.... is much easier to deal with as a Fi-dom... I don't get worn out from them usually.
And in regards to hugging...
If I hug someone or let myself be hugged.... it is kind of a Big Deal for me. For me physical touch is kind of a special thing, and something I only do with people I find special. I also just want to respect other people's space and right to their space. If I am in a relationship then I can be very affectionate. (Very affectionate for me as a Fi user, probably not anywhere near too affectionate for a Fe-user.) So I kind of "save up" my snuggling for the few people I treasure the most. It's like giving them a gift of myself in a manner that few will see.
My ENFJ friend has helped get me out of my shell quite a bit. However, the end result is that I simply show MORE affection for my current friends... I don't expand outwards with people that aren't in my Fi-zone.
I never understood the functions until recently... and it does make me laugh seeing the differences between Fi-user and Fe-user. My XNTP friends are SOO affectionate! I get hugs from them all the time, they will sit close with me on the couch, throw their arm around me, etc. My NTJ friends are so extra reserved. My ENTJ friend gave me a hug a few months ago - first physical touch ever - and it was like such an awkward moment for us. I was like "crap, is John dying?!! Why is he touching me?"
Conversely, I have a customer who is an ESFJ who ALWAYS has to hug me. It drives me INSANE. She reeks of perfume, has this super high pitched voice and yells, "HONEY BUN I NEED A HUG!!" (In my head I am thinking, I need a shot gun.) There was one day that I was determined to move heaven and earth to avoid getting a hug.... so I just kept walking fast away from her... around my store... finally hid in the bathroom for a bit.... came out, and boom! she was waiting for me. Ugh, it's like being stalked.
In conclusion as a Fi-dom person, I likes teh hugz from peapullz ah laks. Ah dun laks teh hugs from peapull ah dun lak.
P.S. I also like to test the waters with people at times... "Aww, you're being so cute I just want to hug you!" Is me scoping out the territory... to see if I did hug them if they would be happy or secretly cringing at the moment.
