I was elaborating on your post because I agreed with it.
Also, using a vibrator with your girlfriend is not a bad thing. There's nothing off with my sex game at all. Most guys feel threatened by bringing a vibrator into bed because they think it's threatens their manhood. If my sex game was "off" I don't think I would hear "that was the best sex I've ever had" by almost every girl I've slept with in the last 4 years. I never used to hear that when I was less experienced. By the way, I'm the one that suggests we get a vibrator and use it, not them.
I agree that "90 percent is in her mind" however some women are harder to get to orgasms then others. You should know that. Some cannot orgasm with vaginal sex alone, that's a scientific fact. The more orgasms you give them the more sexually addicted they become. My current FWB gets like 10 orgasms every time we hook up so a vibrator isn't necessary. My last girlfriend had only one guy in her life give her an orgasm besides me. I was the first to give her multiple orgasms but I don't like having sex for over an hour. Using a vibrator helped give her multiple more quickly. All I have to do to make her horny is look at her.
I'm not breaking things down scientifically either, I'm elaborating so newbies can understand better. I agree with the PUA marketing thing 100%. Guys are trying to make money, so they try and get others to "believe" their way is the best. When actually many ways work, and all the tricks are just gimmicks to make money.
