Fruit picking is what causes lesbianism in prehistoric hunter-gather female groups. Since women traditionally stay back at the cave and go out and pick fruit while the men go hunt meat, they hang around each other alot and that leads to fun with the "fruit" and therefore to cave-women lesbianism. (Its a New Zealand thing)
A homosexual man who not only partakes in the act of anal sex (sodomy) but also 'picks the fruit', in other words folates and handles the male genitals in a manor that some would call sensual or erotic.
