When I was in my early 20s, sex was amazing. I could orgasm several times in a row by just vaginal penetration. At the same time, my clitoris was so sensitive that it pretty much hurt to directly touch it. 

Fast forward through Fibromyalgia diagnosis and a horrible effect from the Nuva Ring, and I am now late 20s. 

Now, sex vaginally is great for about 10-15 seconds and then the pleasure just turns to a sensation of something being in there, and my clitoris has become the main source of orgasm. I can orgasm by clitoris alone, both clitoris and vaginal (the best ones), but not vaginal alone. 

I have excellent pelvic muscle control throughout the entire area, so that is not the issue. 

Has anyone experienced something similar and is it possible to regain vaginal sensation? I just want to be able to orgasm again from regular sex :/
