From John Mayer's Playboy Interview:
MAYER: I’m a self-soother. The Internet, DVR, Netflix, Twitter—all these things are moments in time throughout your day when you’re able to soothe yourself. We have an autonomy of comfort and pleasure. By the way, pornography? It’s a new synaptic pathway. You wake up in the morning, open a thumbnail page, and it leads to a Pandora’s box of visuals. There have probably been days when I saw 300 vaginas before I got out of bed.
PLAYBOY: What’s your point about porn and relationships?
MAYER: Internet pornography has absolutely changed my generation’s expectations. How could you be constantly synthesizing an orgasm based on dozens of shots? You’re looking for the one photo out of 100 you swear is going to be the one you finish to, and you still don’t finish. Twenty seconds ago you thought that photo was the hottest thing you ever saw, but you throw it back and continue your shot hunt and continue to make yourself late for work. How does that not affect the psychology of having a relationship with somebody? It’s got to.
PLAYBOY: You seem very fond of pornography.
MAYER: When I watch porn, if it’s not hot enough, I’ll make up backstories in my mind. My biggest dream is to write pornography.
PLAYBOY: How did you become a self-soother?
MAYER: I grew up in my own head. As soon as I lose that control, once I have to deal with someone else’s desires, I cut and run. I’m pretty culpable about being hard to live with. I have had a good run of imagining things into reality. I’ve got a huge streak of successes based on my own inventions. If you tell me I’m wrong or that I’m overthinking something, well, overthinking has given me everything in my career. I have a hard time not looking at anxiety disorder as being like an ATM. I can invent things really well. I mean, I have unbelievable orgasms alone. They’re always the best. They always end the way I want them to end. And I have such an ability to make believe, I can almost project something onto my wall, watch it and get off to it: sexually, musically, it doesn’t matter. When I meet somebody, I’m in a situation in which I can’t run it because another person is involved. That means letting someone else talk, not waiting for them to remind you of something interesting you had in mind.
PLAYBOY: Masturbation for you is as good as sex?
MAYER: Absolutely, because during sex, I’m just going to run a filmstrip. I’m still masturbating. That’s what you do when you’re 30, 31, 32. This is my problem now: Rather than meet somebody new, I would rather go home and replay the amazing experiences I’ve already had.
PLAYBOY: You’d rather jerk off to an ex-girlfriend than meet someone new?
MAYER: Yeah. What that explains is that I’m more comfortable in my imagination than I am in actual human discovery. The best days of my life are when I’ve dreamed about a sexual encounter with someone I’ve already been with. When that happens, I cannot lay off myself.
