Toys are a great idea - to use with your partner or alone if he's not into it. I think being able to identify that the over stimulated feeling is part of the disorder and not that there is anything wrong with your relationship is a huge step. I still let myself fantasize about others, but I always bring it back to my husband - meaning, I will let my mind wander with someone else but then I swap out that other person in my mind with DH. That way I am not artificially building someone else up and increasing the temptation to cheat. I also sometimes read erotic fiction, but again, I always make sure to end with thoughts of DH. One more tactic I use to prevent myself from cheating is to think of the reality if I were to cheat - it's a fleeting satisfaction. The reality would be a mess. I would feel awful for having hurt DH and screwing up my kids' lives, the other guy really isn't all that great (for x, y, z reasons), I really don't want to live my life with anyone else - couldn't imagine *not* being with DH, DH really is a great guy (for x, y, z reasons), etc. The feeling will pass - I guess that's an upside to bipolar.
