YVRguy saidI'm with you; I think it's creepy to the point of being bizarre unless the person is immediate family or close friend (and even that would be a bit socially awkward). If it happened to me my first thought would be that I am dealing with someone who isn't all there.
Either not all there, or too full of himself or his liquor, or both.
There are different kinds of drunks, including the happy drunk, grumpy drunk, sleepy drunk, talkative drunk, know-it-all drunk, belligerent confrontational drunk, etc. And among them also is the sloppy drunk, who wants to get in your face and put his hands all over you.
That may be what's driving some of these experiences being related here. But that's not what I'm talking about myself, because I don't waste my time with bar or party drunks under any circumstances.
Back when I was cruising the last thing I wanted was a take-home drunk. And his unwanted attentions towards me were depriving me of time with sober guys having real potential, and even scaring them away if they saw me bothering with a repulsive character like that.
So yeah, beard or other inappropriate personal touching can be a warning sign, of creepy personality traits or a guy under some kind of influence of which I want no part. Unless, as I wrote previously, he's already on my radar, and then a touch can make me purr (but still not not from a drunk). Relationship consistency is not one of my strong suits.
