The same as it was when they were actually used. As long as a person’s body can move, there’s ways to gain genital stimulation.

Not that we’re limited to genitals as far as that goes. The anus and nipples are capable of intense pleasure as well. Both men and women can orgasm from various levels of stimulation to the anus, though not as reliably so without internal stimulation.

There’s both men and women that can achieve orgasm from nipple stimulation. Which is both really cool, and really annoying to those that can.

It’s also important to note that men can orgasm without ejaculation, which is often the case with those that can orgasm from external anal stimulation.

Seriously, if a given person can achieve orgasm, there are a dozen or so ways to get there without hands on stimulation, and even more with the hands available. I used to know a guy that would have non ejaculatory orgasm when he would use a bidet long enough. I had patients have orgasms, ejaculatory or otherwise, just from being bathed even though the contact was pretty minimal time wise.

Humans are built in a way that allows for some pretty interesting routes to pleasure.
