I don't know but the emphasis on pulling out and jerking off on her, whether it is oral or intercourse is just dumb. It ruins it. Also, intercourse begins with oral, not ends with it. And let's just go ahead and get that spitting on each others genitals out of the way too while we're at it. WTF? If you have to resort to spitting you need to stop watching porn and start practicing. Anyone who looks to porn as a how to guide is probably going to be a lousy long term lover. But, eh, to each their own I guess.
