@Ash_Anyday It's OK to have darker days. What really matters is what you said "I'm still here!". If you ever find eternal happiness, let me know how you found it. Just remember you make others happy.
@MoogleMilkx That's where experience and care come in. I've thought a lot about this question, as the recipient id look for the other to gauge how far to push me. As a spanker, I'd be using how I'd feel in that situation alongside physical reactions and communication.
