Touching yourself without realising

I unconsciously touch myself. When I’m studying, reading, on social media, doing anything really, I stimulate myself with my hand usually over my underwear or I press my heels there. I don’t even realise I’m doing it. I also get this weird feeling there whenever I’m nervous so I press my heels there or cross my legs to calm it a little.

Does anyone else do this and does it count as masturbation? Because if it does I may be addicted to masturbating...

please let me know
