I'm looking for the names of three movies from the early 80's:
1. The first one dealt with a rich, young girl that wasn't able to orgasm with the men she had been with. She hooked up with a girl at her house who made her orgasm. And then one night, she got drunk at her house with the fat guy from the gas station she frequented and he finally made her orgasm. There was also a scene where she took her friend to a ranch and one of the ranch hands took care of her friend.
2. The second film involved three guys, I think, that went camping, and each one was visited individually by one or more of these virgin muses dressed in white. After each woman and camper were finished, the woman would disappear. I'm pretty sure that Peter North and Steve Drake were in it.
3. The last film starred Ron Jeremy as a sheik who bought "spanish fly" from a "doctor" (Sharon Mitchell I think) and brought girls onto his house boat for "experiments" with the "spanish fly". Ron and his sidekick got with a number of women and even slipped the "spanish fly" to the "doctor". At the end, she finds out and slips it to Ron and his sidekick. The movie ends with his sidekick chasing him around the boat.
