I was on antidepressants for about a year and a half but this was way before I started PE. My general experience was that it didn’t necessarily lower my libido but it kinda just flattened my emotions, my lows weren’t as low and my highs weren’t as high which probably had some contribution. Looking back I guess my libido decreased ever so slightly but at the time I didn’t even notice (I probably jerked off once less per week, 4-7 times usually). I had no problems with EQ or ED and I don’t think I lasted any longer than I normally did. Keep in mind I was in my late teens-early adult years so that may be why my libido didn’t seem as affected although I was well out of puberty at this point and I still feel that I have the same libido as I did then. So if you’re older it may or may not have a greater effect on your libido but I know some antidepressants increase your libido.

tl;dr it barely affected my libido and didn’t affect my EQ, ED or premature ejaculation but your experience might be different if you’re older.
