Patient: I am 31 years old and not in a relationship but I sexually pleasure myself. For a while now, I have had soft erections, trouble maintaining them, and no pleasure during the act. I had my Testos. levels checked and I was low-normal. I thought it was because I take paxil, which is known to lower libido, so I began taking well-butrin, but I still have problems. My thyroid levels are normal and I have been tested for klinefelters and don’t have it. What other answer could there be? Am I just not meant to enjoy sex? i’m very depressed about this.
