Lecher(1973)

Ray, a lothario and general pig of a man, has no problem coaxing all manner of women into his carnal web, be it an English governess, wealthy society lady, or even an innocent Girl Scout. But when Sandy, a sweet young hostess at a pizza parlor, tries to get him to take a more serious and romantic approach to his frenzied sex life, Ray begins to second guess his ways… is he truly capable of change?
