I’m not huge of cuddling and tend to get overheated easily when I do, but I find it really pleasurable (non-sexually) when my wife runs her finger/fingernail on my hand or arm. Just light touch in general feels incredibly stimulating, but it’s kind of a weird thing to outright ask for so I just kind of enjoy it when it comes around. I also like when my kid steps on my arms or legs when climbing on me. I should probably look into massage therapy.
