I have some Mandingo on video and I like his huge cock.
Unfortunately, Mandingo stars in straight porn, which means the focus is always on the women. His cock will almost always be hidden by female hands, female breasts, and more females--even though the video packaging focuses on the huge cock. Straight porn is basically a rip-off if you want cock.
I do wish straight porn stars would do solo scenes. However, they know it will be mostly viewed by gay guys, and that would ruin their straight image.
