You are fortunate that your woman is not one to lie about and fake orgasms. How can sex possibly improve if she has made you think you were already a sex god?
It is true that many women may be satisfied just with the intimacy of the act without the orgasm - I have been told this and seen it referenced many times.
Dr Ruth Westheimer says that the attitude is that every one is responsible for their own orgasm. That may mean that they must see that they get the type of stimulation that they need for it.
After reading through this thread it sounds like the main problem is a medication. Probably an SSRI.
Some possible solutions:
-Is a drug still needed?
-Can the dosage be reduced?
-Can it be changed to one with less or no sexual side effects.
-Trazadone or wellbutrin are two examples of drugs with no effect on ability to orgasm - in fact they have been noted to restore the ability to orgasm in persons who could not be taken off SSRI’s when simply added to the regimen (Although I think simply switching to one of them would be a preferable alternative if appropriate).
