Hot Moves(1984)

Overview:

Four friends, annoyed at how almost everyone else they know is having sex but them, agree to do what they can to help each other lose their virginity before the end of the summer. Most of their opportunities are foiled by their inexperience and bad planning. Michael, the most sensible boy of the foursome, really just wants to stay with his long-time girlfriend and take their relationship to an intimate level, but after putting him off for six months he grows impatient and splits up with her to seek his fortune elsewhere.
