Having already posted here how I'm not a big fan of kissing anyone, not just guys, at least not long & passionately, I'll tell a contrasting personal anecdote.
At the close of my Army career, and subsequently coming out 6 months after my retirement, the oddest thing began to spontaneously and subconsciously happen to me.
I'd be sitting at a big conference table having a meeting or briefing as usual, with a dozen or so fellow Colonels, Lt. Colonels, and sometimes a General Officer present, and I'd suddenly get an urge to kiss the male Officer sitting next to me!
and a few months laterusly! I'd be staring at his handsome face dreamily (and gawd, can buff, mature men in their prime, wearing a military uniform, look hawt!), and I'd suddenly involuntarily lurch for his cheek with my lips. Thanks heavens I always caught myself at the last moment, or I would have been taken out and summarily shot, I'm sure.
What I'd do to cover myself was to continue the lurch down to the floor, excusing myself loudly that I had dropped my pen.
It was the strangest thing, and I've never had this kissing reflex happen again in my life. I've since wondered if it was my inherent gayness bursting to be finally set free, which finally happened a few months later. But whatever the explanation, I apparently had an overwhelming urge to kiss a man very, very badly!
And a few months later I finally did. A thrill, of sorts, but still not my favorite thing. As I said, I'm just not a kissing guy.
