Watch The Chain Reaction (1996) Official Trailer

a sexual awakening, a lost virginity, a chain of desire

Daniel (Johan Paulik), an innocent and cute young guy, enters a gay bar for the first time. The bar's quiet and Daniel is clearly transfixed by the barman. He can't take his eyes off him. His trance is broken by the arrival of the barman's boyfriend who is also young and pretty, but obviously more confident than the naive young Daniel. At first he's amazed at their sensuous kissing across the bar and then he's jealous.
