My hugging/kissing friend makes me uncomfortable.
I'm a 28 year old woman and I have this older male friend who used to be a coworker. I'm still really cool with him, we see each other around town and sometimes he shops at my new job. Every time he sees me though he'll give me a big hug and *cringe* a kiss on the neck. I know this sounds totally creepy but I don't think he intends it to be; his whole character is one of platonic friendliness and he's just really fond of me because I used to help him out a lot at our job. He's NEVER hit on me or asked to hang out outside of work so, I don't think the kiss thing is meant to be frisky, I think it's something he probably does with everyone. But it does make me uncomfortable. He even did it once at the library when I was there with my boyfriend, and my boyfriend was understandably put off by this old bearded guy giving me a big hug and a kiss on the neck lol.
How do I let my friend know that this makes me uncomfortable without hurting his feelings? How should I phrase it so that it's not awkward? He's a terribly nice guy and I don't want to make it seem like this is something that's been bothering me a long time (which it has.)
