If Mark was turning gay tonight, then he was being very choosy about it. A fit, good looking young man like him immediately attracted attention. He was a new kid in town and quickly had guys offering him drinks and other substances. But Mark wasn't interested, yet! If Mr Right didn't come along tonight, there would be other nights. Mark scanned the club and scanned again. Then he saw what he was looking for. The trouble was, his choice came across the club to the bar with arms linked with another guy.
This might be rather difficult if not impossible.
