Why people watch softcore porn?

I prefer soft porn than hard core porn because the flow of the story is more of mental than visual. And I'd say visual is lesser in sensation when it comes to titillation. It's just like being in a nude colony when the appetite for sex would vanish because all you see are nude people. But when you go to a strip tease joint and you see only the panty and bra and being teased of what's inside, the impact is much greater in terms of sexual stimulation.
