1. Not so much personally. But I do appreciate it when I am asked about my Kinks (which of course should be laid out beforehand) and my hobbies.
2. Always when I'm working with someone new. A 15 min gentle massage and get to know each other type chitchat always helps to break me down a bit
3. I prefer dim lighting, no strong artificial scents or particular noise. this may vary though with the type of visit.
4. A hug is great. Being immediately collared, leashed, and pulled to the bed (or wherever) is my favorite.
5. goodbye hug is also great. Text is a plus. If impact was involved, I like sending them a picture of their handwork.
