All orgasms are not created equal. Many of us know this without needing statistics to back it up. The human body produces 400% more prolactin after sex with a partner than if just masturbating alone. You are still having an orgasm, yet it is simply more pleasurable with another person and the body reacts as such.
Once I got into phone sex, I quickly realized that masturbation alone was like black and white, phone sex was like technicolor. It’s physically the same sensation yes, but emotionally it’s totally different. No one should masturbate alone, it’s so lonely in comparison! It’s like lettuce and steak, both might fill your stomach and make you not hungry anymore, but which would you rather have? Steak, of course!
Talking and interacting with another person makes it a totally different experience, even your body knows that from the hormones it secretes, it’s just a better experience. Once you have experienced both, I cannot fathom who would prefer alone. Many guys have masturbation buddies they watch porn with and have fun with, they are not touching each other, but they are doing it in the same room and getting more aroused knowing another person is doing it at the same time, it heightens it and makes it more pleasurable. It’s a shame more people don’t have fun with their friends in such a manner! Not everyone is comfortable doing something so private in the room with another person, if people loosened up they’d have a lot more fun for sure!
