I am on the other end of the spectrum somewhat. I am on Focalin XR 10MG currently, it reminds me of my self medication/rave daze playing around with Ecstasy. Super aroused emotionally/internally, but no real desire to physically act upon it. Very odd to describe, but the previous times (illicit drug use 20 years ago) I did become intimate, it was a very strange orgasm, best described as not as physically fulfilling as when sober. Perhaps close to what you are describing?
Are you indicating you feel bad physically or emotionally, such as guilt, post orgasm?
