I took SSRIs for a year in my late twenties. They had no effect on my depression, but resulted in permanent sexual dysfunction. My own fault for not properly researching the potential long-term side effects, I suppose, but it certainly wasn't raised as an issue by the prescribing doctor either. I hope someday there will be cure of some kind.
I have a very understanding spouse, luckily, but I'm honestly devastated in not being able to accommodate this dimension of our relationship anymore.
Recently, my GP offered to prescribe me antidepressants again for an episode of burnout, but I'm absolutely not keen to go down that road again. I get that it's cheaper and more available than therapy, but I've been burned before.
