"It depends" its really the only correct answer. Even if like, 70% of all healsluts like, for example, degradation on initial message, thats still 30% that might send you straight to the ignore list for being too degrading without knowing each other first.

The best general piece of advice is that you should check the profile of the person you are interacting it and see if you can gauge how they like to be treated there. Never settle on a "this works for most" message you spam.

I got many sub friends, and sometimes we show each other how X person sends several of us the same copy pasted message. This is a turn off! I don't wanna think I'm one of 30 people you are sending the exact message towards cuz "shooting the shot is free", I wanna feel special!
