Getting hard is a matter of hydraulic pressure. Don’t need gravity for your heart to pump blood, and ejaculation is a mechanical action, like swallowing.

Thought you couldn’t get it up in zero G - and even If you could, we don’t actually know if the mechanisms needed to ejaculate would function in zero G.

As far as I know, everything would work fine. If it’s something you can do right-side-up, up-side-down, or prone, and in each orientation it works exactly the same way, it should work in zero G. It’s just hydraulics anyway. Not gravity dependant.
