Mirage, I'm sorry you're going through this, but know, you are not alone. This has happened to many entering into a r/l D/s relationships (submissives as well as Doms). I really don't have a lot of advice to give as I'm fairly new but the other posts have a lot of great advice. The cravings will still be there, just be careful and use caution before attempting to assuage them. Please don't ignore the fact that he's in another relationship (unless you're fine with poly). Polaris's post in particular has a wealth of information. Read as much as possible about D/s and BDSM, especially "sub-frenzy". This lifestyle can be very intoxicating especially if you were like me "very vanilla" and have a strict and/or conservative, religious background. Take care...
