I don’t like hugs.
It’s nothing about the hugger, nothing that anyone should take personally. I just don’t like hugging.
I don’t think most people appreciate how much interpersonal skill goes into giving and receiving hugs. What if one of you is sweaty? What if one of you is stinky? How long is a hug supposed to last? What if the hug is misunderstood as a gesture of sexual interest? What if I’m hugging a man and he gets an erection? Am I allowed to notice? Where do the arms go? Do I put them around the neck if someone is taller? Do I wrap them around the back and do a full frontal? Most importantly, consider what I look like. I’m a short woman with larger-than-most boobs. This is really the crux of the situation.
