Scarleteen

Hello again.
So I have this question for you Scarleteen.
I know that some people wouldn't feel an orgasm when they ejaculate.
But, can a man feel physically nothing (in the penis or any part of the body) when the ejaculation occurs?
Like, would a man ejaculate (when he's awake) but didn't knew he ejaculated?

Thanks.

Upss, specifying, either in masturbation, manual sex, or intercouse.

It would be pretty unlikely for someone to ejaculate without feeling anything at all, or not notice that they had ejaculated.
