If you really want just hugs then how about asking for hug from family member or a close friends?

and people dont normally randomly hug each other, someone allways have to start it and if it has to be you then you just wanted the hug more than they did nothing wrong with that.

So keep on hugging and they will realise that you are huggy person and start to get courage to hug you back on their own.

ps. my suggestion is risky if you hang out with friends that are not very sentimental.
