So che è facoltativo, ma che senso ha chiedere queste informazioni?

The point is literally written there.

The only right answer there is…
“I am a pan-demi-sexuell fairy furry who happens to be aromantic but also heavy into BDSM.”

And yes i am aware… that might be not a good answer to get along with those people. But i usually tend to answer ridiculous questions in a ridiculous way.
