I'm not sure if this is an option that you'd consider, but could you manually stimulate yourself prior to your engagement with him, and satisfy yourself (bring yourself to orgasm)?
My wife doesn't have "female anorgasmia", but it's difficult for her to 'get off' in anything less than about an hour. When we first got together, I took it personally and felt like I wasn't "doing my job" correctly. I've come to realize that some women's buttons are just harder to push than others, and we work on it together. I don't get mine until she gets hers, and that's the way it is (unless she says that she's okay with not getting hers, in which case YIPEE!!!).
Jokes aside, I don't see this as necessarily a horrible thing. If you can get him on board, as I've done with my wife, maybe you can get him to start thinking of it as a very long 'warm up' to the main event!
Have you seen a doctor?? Most of the "female sex drive" pills are placebos, but honestly sometimes there's a chemical imbalance (such as depression, even if it's mild and barely noticeable) that can cause anorgasmia in a female. Sometimes all it takes is a little bit of hormone therapy to tweak your chemicals and fix things...barring that, consider seeing a sex therapist. Most of the time female anorgasmia is NOT caused by something mechanical (i.e. you just "can't" physically get stimulated) but it's caused by a whole host of other things, chemical imbalances, psychological considerations, that if addressed can be fixed.
It is a medical condition and does require treatment....so consider seeing a doctor and helping yourself and your husband. you both deserve it!
