One of Colton Underwood's first orders of business as a new openly gay man was to hit the town and dip his toe into the scene -- but it looks like he got distracted along the way.
The former 'Bachelor' -- who just came out publicly last week -- went to a gay bar in Denver Sunday ... a place called Charlie's, which seems like a pretty happening place complete with a dance floor, private booths and bumpin' music.
All that was in full flex while Colton was there .
