I would think this is probably caused by Finasteride, and not by PE. There’s even a name for it- Post Finasteride Syndrome. I likely have something similar- Post SSRI Syndrome.
I’ve never taken Finasteride, but I have a similar situation to you- I took an antidepressant (Citalopram) for approximately 9 years. I went off of it very slowly last year and completely stopped in April of 2020.
Right after I quit, it was extremely difficult for me to get an erection, and when I did, I had premature ejaculation really badly.
Fast forward to now- my erections are better, but they’re still noticeably different from before I went off the medication. I can get erections, but they are hard to maintain, so I often have to take Sildenafil for sex.
Doctors are surmising that Finasteride Syndrome is similar to Post SSRI Syndrome. The symptoms are extremely similar, and both can mess with your hormones.
I went to one of the top urologists here in Germany who sees patients that deal with both Post Finasteride/Post SSRI Syndrome, and he very much believes it’s real. He did tell me that all of the patients he sees do eventually recover. Unfortunately, he couldn’t give me any kind of a timeline.
What is strange is that my hormones also seem to be ok, and none of the tests really found anything out. One of the major side effects that I still have is that it’s extremely difficult for me to cum. I can orgasm, but very often, there is no cum. I never had this problem before going off the meds, so that’s also how I know it’s not “just in my head”. You can’t fake not being able to cum. Even at the urologists office, I had to give a sperm sample, and they noted in the report how small the sperm sample was.
What worries me is when you read message boards on the topic of these syndromes, some people seem to have had these conditions for years after taking these medications with little improvement. I would recommend not to read them, because it’ll only depress you.
In the meantime, I’ve been doing a lot of HIIT exercises, going to the gym, and taking things like Maca pills, Muira Puama and Citrulline. I think that has helped some. Unfortunately, my erections still aren’t back to baseline, and I just turned 36. So it’s extremely frustrating, I definitely know how you feel.
