I'd really encourage you to have regular orgasms, at least several times a week, with and without H. During sex with H, or more likely before and/or after IC, you should almost always have an O. And, if you don't already own one, buy an eroscillator.
The more *satisfying* sex you have, the more you will want it. I doubt many men would be interested in sex if they did not experience orgasms as a result. Women are no different. Once you aren't desparate, sex becomes rather tedious if it is one-sided.
Going through the motions sex isn't going to be good for anyone. Own your sexual satisfaction and make sure it happens. And, by all means, if you have been faking Os, stop immediately and come clean with H.
