Was flippin thru cable channels. Stopped at this movie which had an interesting premise...

A couple go the greek isles and the man
hooks up with this lone greek islander
for a romp. Then he tells the girlfriend what happened and she ties to do the same...

Picks up a young greek stud and goes back to his place...the guy puts on "Sexy Dancer"...very appropriate for his impending seduction. She chickens out and leaves.

Then they get invited to a swingin' boat party..everyones nude and wacthing a drag
show...then "Sexuality" plays while all frolic into the water.

This movie is from 1982...Summer Lovers

Yes
I remember Peter Gallagher's
