You're not the only one. Touch is what all human crave in some shape or form and makes us feel comforted or loved. I think it makes sims feel more human and like they care for eachother. Sooooooo many things I would love to see that would make sims more alive. And not particularly romantic interactions but just affection for all ages.
Would love for example floor cuddling so that sims can cuddle on the floor in front of the fireplace,
Sims being able to feed eachother but not romantically like we have, a friendly feed. In my culture it's a sign of affection to give another a bite of food with your hand. A friendly category (family) kiss, a forehead kiss, one sim being able told actually hold another not like the quick hugs we have that are 1 second, kids being able to sit on parents lap and watch TV. (I was trying to show a picture of what I mean but imagr is not working for me. But just googling something like family watching TV with kids shows all kinds of examples) sims being able to give a cooking sim from behind a hug, sneak up on a sim and give them a surprise hug and/or cheek kiss from behind, piggy back rides, sims lying their head in another sims lap getting their hair caressed. Just those things that make you go awwww ?
I always wanted to see sims care for other sick sims instead of just having your sim buy meds online. Have your sick sim rest in bed while the other sim checks for fever, brings soup, gives a little comforting caress and things like that.
It's really those seemingly meaningless gestures. Touching and affection humans do with eachother all the time that means the most to me.
