Thyroid disorders are not typically a significant factor for libido or orgasm. A bigger issue is expectations: The majority (probably at least 80 percent) of women cannot have and never have had an orgasm with intercourse alone. Most women need more direct stimulation. As we get older and in the absence of estrogen, having an orgasm without direct stimulation becomes even more difficult. It may not be realistic to expect to have an orgasm with intercourse or penetration.
A vibrator can be a great addition for that direct stimulation. You might want to try one with a warming lubricant, and see what happens! The Gigi2, Liv2, and Siri2 are three options we have offered at MiddlesexMD that have more intense stimulation than some others on the market. I have seen some amazing results from women who hadn’t had an orgasm in years because of medications that interfere with orgasm or medical conditions that make orgasm more difficult. They were successful using these products, so give it a try and good luck!
