Seriuosly UkEng there's no harm to Hug people. You dont know how many people never hugged or have no one to hug. One should not see this from his dirty mind only (I am not referring it to you).

With a simple hug you can give a smile a satisfaction that may last for long. I wish we can do this some day. The joy I feel when I hug someone is amazing, cant not explain in words.
