Tony:
Tony's kisses are hot and passionate. There are three types of kisses from tony...
1)behind closed-ish doors...
2) more meaningful/ out in public kisses...
3) quickly when nobody's looking and he wants to have a quickie somewhere that is definitely not meant for that sort of thing...
Bucky:
(Tws)
Kisses were passionate but still a bit steamy, kinda like Tony's but turned down, a lot.
(1940s)
Kisses were just straight up passionate. No flirt just love.
Peter:
Kisses with Peter were timid or nervous yet loving. Since it's the first time both of you had been in a pretty serious relationship you were all new to being intimate.
Loki:
