I'm a mid-30s male taking Zoloft (Sertraline) for anxiety, 25 mg/day. When I initially started the meds, it seemed like it was a little bit harder to ejaculate during sex, but that seemed to subside after a week or so, and I've been fine for a few months now. However, the other day, I simply couldn't finish. One thing that was different this time was that it was in the morning shortly after my dose of Zoloft (maybe 30 minutes at most). Are sexual side effects stronger immediately after dosage, then subside as the day goes on? Or was this just a random occurrence?
