Edging Together With a Partner on Mushrooms

A friend suggest we do edging together on mushrooms.

I'm not sure what he means because edging to me is self pleasuring. For eg. A man might stop himself orgasming and just goon/self pleasure all day. This is good for those practicing semen retention

For a woman, this might mean coming over and over in self pleasure. I do this sometimes.ie,just have one orgasm after another while watching a documentary or sth 🤣😜

So what would be edging together with a partner entail? ( On amplifiers....) Masturbating together?

That could be fun.

He also mentioned conversation in there😆

Suggestions welcome. 🤗 😁
