Why do I constantly crave hugs?

I constantly feel the need for hugs and physical contact and I don’t know why. No one in my family is like this and I’m concerned slightly. I cannot go day today without some sort of physical contact or reassurance through touch. I don’t think it’s from being touch starved unless there’s something with my brain that makes me more prone to that. Any ideas?
