A list... Fuck, let's see
- Kissing sounds obviously up there.
- As a derivative, mouth sounds. They're not explicitly kisses, but the sound is similar.
- Wet sounds in general can sort of tie back to the this. Stirring macaroni is an obvious, but so would be shaving foam (see below)
- Implied physical contact. The majority of men in the West don't have much positive physical contact. If you're talking about holding hands, stroking their hair, "lay your head in my lap" that's going to be GFE. Really truly, if you go to a barber, that might well be more physical contact than anyone else in your life, if you're single.
- Love. Check out script-fills on youtube, it's not uncommon to see the term 'l-bomb' used almost as a content warning, because it's weird for anyone except a partner, child, or parent to say this to a man.
- Similar, positive affirmations.
- Nicknames. Not just referring to someone as a diminutive of their screenname, but having fan-names that are positive. It sounds obvious, but calling chat your partner, honeys, whatever, that's gonna gosling bait.
- 'Sharing' personal life. It's a common problem in partners - the main listens to the woman venting, and proposes a solution. She wanted him to say "I'm sorry that happened", he wanted to try and help. Telling stories about creeps or struggles you have could well move you along the GFE axis.
- Ear blowing, whispering, etc can sort of add to this, because they imply physical closeness. But it depends what you do with it.
