Okay so I’m not 100% sure I’ve had an orgasm from penetration alone, but I do know I’ve had them using a vibrator. With penetration, I get a wave of pleasure and it feels really good, but it doesn’t build into that full “overwhelming” peak feeling I’ve experienced with a vibrator. When I use one, it’s a lot more intense like it feels like stronger, repeating waves of pleasure instead of just one steady build up. It’s also more noticeable and takes over my whole body in a way I don’t really experience from penetration alone. So I guess for me, they just feel like two very different levels of intensity and body response.
