Thanks for this forum, very helpful.
I am born in 1979, my story:
I suffered from depression at the beginning of 2019 and took Escitalopram, 10mg/day. The only side effect was difficulty to have orgasms. Switched to fluoxetine in May, with less libido and some ED.
I stopped in September. After 2-3 weeks, sadness came back, with a bonus: persistent difficulties to sleep. And still low libido and some ED (my first PSSD?). Doc gave me 3 months of Mirtazapine, from November to January. Sleep came back. I am not able to tell if my libido rose or if I just got used to it. I stopped while feeling ok.
For no good reason I took Escitalopram again, 5mg/day, then 10mg/day during confinement. After two months, and just after starting hairloss treatment (I don't think this is related, that wasn't finasteride! see viewtopic.php?p=36602#p36602), I felt a sudden loss of libido and strange feeling within my penis. I switch immediately to 5mg/day and stopped 3 weeks later. It was in the beginning of May.
Libido arose a little in May, while starting a one-month affair. This made me feel something was wrong (low libido, mild erection, low pleasure... I was unable to use condoms but, as we were both tested clean for viruses, we did without) but being only "half" me was enough to have fun.
This affair got me Chlamydia and I was cured (tested clean) by antibiotics in the end of June.
From this time, things have been more or less stable (and worse than in June):
1 - Libido: I have very low libido (for the first time in my life, even in my worst depression) - I only feel a very slight desire when kissing / touching a girl
2 - ED: I can have a 50%-erection by thoughts while thinking to my craziest fantasies (before I could get a full erection with any sexual thought). Mechanical stimulation combined with fantasies can get me a 80%-erection, enough to make love, with some difficulties.
3 - Numbness: I feel like my penis skin does not feel anything, but I can feel when contact is though. My orgasms come with low pleasure...
4 - Sleep: I fall asleep but wake up early
I feel less desire and pleasure in general: art, movies, music... except for food (strange? I desire chocolate more than ever) - this came in June.
EDITS: I have seen some people use their topic to log evolution of their symptoms, I find this interesting. So here are my reports.
Note written in August #1: I tried to look back to document early stage. Not very scientific, though... Imaginary report from June 17th:
1 - Libido: 30% - low libido - I felt a slight desire when thinking about sex and had some ideas about it (better than last weeks taking SSRI)
2 - ED: 60%-erection by thoughts / 90%-erection adding mechanical stimulation
3 - Numbness: feelings were wrong, orgasms were ok but not awesome.
4 - Anhedonia: was less interested in arts and didn't feel much. Motivation was lower but ok.
5 - Love: still had some (decreased) feelings for girls and my family
6 - Sleep: ability to fall asleep OK, but some early awakening
NB: at that point I was not aware of PSSD. I just noticed these symptoms and was otherwise very happy in my life. Nothing psychological, I think.
July 11th, 2020
Sex
Libido: 0% (no thrill at all)
Erection by thoughts: 0%
Erection by mechanical stimulation: 50% (not so hard but ok)
Pleasure: 10%
Anhedonia: Pleasure while listening music: 10% (I still have reflexes to dance but I don't feel anything while dancing)
Things have been stable for one month. Was better before (no anhedonia in May, higher sex drive)
Note written in August #2: I was having a psychological crash when writting July 11th report, discovering PSSD. I was much better just before or after, so this report should have been:
1 - Libido: 20% low libido - I had rare moments where I was slightly thrilled
2 - ED: 50%-erection by thoughts / 80%-erection adding mechanical stimulation
3 - Numbness: skin doesn't feel very sensitive, orgasms come with low pleasure...
4 - Anhedonia: able to feel some emotion (still crying when something is sad) but no pleasure, etc.
5 - Love: blunted... but some feelings
6 - Sleep: ability to fall asleep OK, but awakening often 4-5 hours later
*** I started a daily 30-minute run and probiotics and food supplements (vit D) ***
August 16th, 2020
1 - Libido: 10% very low libido - I only feel a very slight desire when kissing / touching a girl

A: Skin doesn't feel very sensitive, not sure about that
B: Orgasms come with low pleasure (within normal range? difficult to tell, alone...)

December 1st, 2020
I am feeling "low but normal" on these issues:
4 - Anhedonia
5 - Love
6 - Sleep
Stopping my report about them.
Regarding sexual function, it had ups and downs this month, from my "october 30th" state to my "september 10th" state. This can change in one day... I don't see any explaination.
December 21st, 2020
I must admit I have been stuck in the "low" state for one month...
1 - Libido : I don't think about sex, except when with one partner. Low drive, low fantasies.
2 - ED : 80% OK
3 - Numbness : low pleasure, week orgasms
6 - Sleep : I tried to reduced hydroxyzine and I can tell sleep is still bad without medication
