Ordinarily, chat would be up and you could ask there. But you can ask here or anywhere, really.

If it is a question about submission that subs could help you with, you might try the submission Q & A section of the Library:
http://www.bdsmlibrary.com/forums/fo...or-submissives

If you seek more information of Dom/mes about Domination and safety, etc. you might try Q & A for Dominants:
http://www.bdsmlibrary.com/forums/fo...-for-Dominants

If those don't help, find some O/one you think you might talk to and address T/them directly for information.
