However, how do you know that the females are receptive?

Are you serious? Have you watched bonobos or other monkeys?
You mean, you could tell she wanted it by the way she was dressed? Sorry Holmes - that was mean of me. But I like to watch monkeys at the zoo, too, and I still have no idea what you're talking about here. If there's some kind of obvious behavioral cue for female sexual receptivity that you're picking up on before actual penetration occurs, I think you owe Schraf and your readers a little more than arrogant derision.
In regards to monkey masturbation - I've heard stories about it that indicate, to me at least, that it could be a sexual display. A kind of "conspicuous consumption" as a display of virility; "I'm so virile that I can waste it if I want. Here, see?"
Just a third alternative I'm throwing out there.
