Well it is probably the most distinguished part of the penis.
It does look pretty kinky though, when the male, preferably an oversized monstrous beast plowing into a female protagonist or heroine, with the spongiosum visible, pumping semen into her, half/half on consensual terms, in pulsates rhythmically, in any given animated form, while in a reverse cowgirl or mating press position. But thats just one of my kinks.
