SSRIs absolutely destroy sex drive and ability to enjoy it for a frightening large fraction of people. For people that take them for extended time that sometimes becomes permanent! People should know the tradeoff they're making and not make the decision lightly.

I recently learned a possible mechanism that could explain this especially in men. Some SSRIs can make men's prolactin levels skyrocket to multiples of the normal value for men and this effect seems to sometimes persist for months after. I've found inconspicuously worded allusions to this in open medical literature, but it doesn't seem widely known or studied. Much of my knowledge is anecdotal from seeing friends and families before and after bloodwork. If they weren't privileged people with great health insurance they would never have gotten the labs to know that the havoc wreaked on their hormones. I'm wildly speculating, but I wonder if SSRIs might have a tendency to cause small prolactinomas to form which would explain the persistence of the harm.

Yeah. I don't have as much of a drive, but I haven't really had any problems with sex. I think it helps that my lovers and I have pretty crazy sex so it is rather easy to get excited :)
