I'm going to respectfully disagree, and I'm only talking about my own experience.
Men ejaculate all the time. Men cum all the time. YES. Obviously.
But having a true orgasm? NO. I think it happened to me 2 or 3 times in my life. The first time it happened to me, I was really like WTF is going on!?!?! My whole body started acting weird and I was shaking for minutes, literally. If this is what women experience when they have an orgasm, they are so lucky. You are not in control anymore. It is an indescribable feeling. I must have ejaculated a bucketload of semen. It's so fuzzy... I never really understood WTF happened.
My guess is if men want to experience such a devastating orgasm, get the girl to put a finger up your butthole and play with your prostate... only I'm not the kind to enjoy the idea lol
