We have an OPP which applies only to me (F). My partner is M and bisexual and can see whomever he wants. I am bisexual but limited to women. I don't like it and he is well aware that I don't like it. He is also not going to back down from it and on the grand scale of things, I don't consider it a deal breaker so I accept it. However, he has told me he doesn't want there to always be an OPP so maybe someday it will change.

I think you first need to decide how important this is to you, OP, and then find out how important this is to your husband. Then you can either begin to work on the issues at hand, reach a compromise, accept the OPP, or whatever other option works for you guys.
