When I was on Zoloft, it took AGES to ejaculate and sometimes I couldn't even get hard. This only changed when I stopped taking it. Sorry.
But you know, mental health is important and you won't need anti-depressants forever.
I'm not a doctor and so can't reccommend you any alternative anti-depressants. Talk to your doctor about these bad side-effects.
