This Video explain that in Islam, the listener's status is very high. The speaker is only allowed to touch someone they are married to or related to. To touch the listener without that relationship would be regarded as very rude. The speaker assures the listener not to take it negatively, as it is about respect rather than anything else. The listener's right to say who can touch them is believed to be only up to the listener themselves, and ideally that should be in the form of marriage.
