Cool Movie Trivia

I remember watching an old softcore porn movie where a young man must track down his uncle's former lovers. The young man ends up having sex with all of the women he tracks down. In the end, the last one he found he fell in love with and had a baby. If I remember right, he was trying to find something so he could get his inheritance from his uncle. I don't remember the name of this movie and really want to track it down. Any help would be appreciated.
