The Sexpert(1972)

He has what every woman wants

Hopelessly inept clod Finster Fahrquart desperately tries to get into the swing of the 70's sexual revolution and figure out a way to succeed with the ladies. Following a series of disastrous encounters with such folks as an aggressive farmer's daughter, a not so innocent virgin, and an unhappy housewife, Finster decides to attend an orgy.
