i think I stim on my boyfriend

i know he doesn't dislike it but i think i stim on my boyfriend by looking a lot of body contact, i suddenly have the urge to feel his body, and rub it or feel a bone, skin or whatever i feel like I'm the moment, and i want to figure out if that's stimming or just "normal" behavior cause i feel like when i stim, im not sure if i make myself clear
