I can provide a better full-spectrum sexual experience than any machine.

The John Henry of oral. The question is do you want to go out the way he did?

Didn't you just say its emotional? Then its subjective, and not totally within your control... there is no objective truth to "I am better than a vibrator", its only your ability to match the preference of your partner.

Maybe for you. Your experience with sex is truly just your own experience. People who aren't you experience the world and it's sensations radically differently.
