I was with my bf for 5 years before I started to take medication. We did it on a regular basis and I would achieve orgasm. After I started the meds I felt the same way that you are describing. It was like it went so far and then my body stalled out. I didn't say anything or stop the meds or even change the meds and after about 2 months I was able to finally orgasm again. The only problem now was that it was not near the intensity or satisfaction that it used to be. Also, I would continue to feel like I needed more and if we kept it up and I managed to orgasm again, it would just be the exact same all over again. I started to not want to get aroused because I knew I wouldn't be totally satisfied.
