Wanting to touch people??

Title sounds weird but it's an innocent question. So for some weird reason whenever I'm with friends or coworkers (that I'm friends with- not strangers.)I just want to touch them, like hold hands or hug them. Not weirdly- just affection. The urge to just touch is more strong with male friends. I don't usually do that though cause most people don't enjoy being touched.

Is there some sort of scientific reason for as to why I want to?? Is it just a me thing or do other people just get the urge to cuddle their friends at random too?
