that is one heck of a question yes.
be safe is the most important advice. keep who you are away as much as it is possible.
perhaps go to the chat here and have a discussion in a private chat with some of the known Doms and subs here.
Read as much as possible here and on other places to know what you want and look for in this scene.
Do the sub checklist that Sir Russel(I think it was) posted in the knowledge forum.
Dont go headfirst into something. It might hurt more than you want it to do.
Trust is very much gonna have to come into play but that has to be earned with time.
dont forget honesty with your bf either. he will need to know what you are doing.

I am sure Ill think of more later on.
take care meanwhile
