Exactly. Imagine how our wives feel: they are enjoying hot sex with their lover or bull, and approaching orgasm. Then the cock is yanked out and a guy is jacking off on them, having a nice orgasm for himself. Not exactly the satisfying experience a woman wants. If hubby needs proof of the cum there's a better and more satisfying way. Pull and shoot the first burst on her then quickly back inside to finish in her. I learned long ago that mastery of this technique extends the male orgasm. It is also very sexy for my wife as she knows she caused her lover to lose control and his sperm is on her AND in her.
