No. I think that it would still be bad if it were self-use because it is ultimately doing something that someone doesn’t consent to.

If you were to use this on yourself or someone consenting, I see no issues there - be kinky all you want.

Consent is the core foundation for me.

The reason why imagining someone is different is that it is often less intentional - thoughts are not actions.

Drawing someone to be similar to someone you know is very intentional. Even worse, there is a high likely chance that if you are drawing someone you know naked, you likely never asked for their consent because you know you wouldn’t get it.
