Do all antidepressants cause sexual dysfunction (difficulty reaching orgasm and also other things) for men? are there any antidepressants that doesn't cause it as a side effect? also do ssris have the highest potential of causing it?

No. Everyone is different. Try and see is best. Discuss with local team. You may want to go to Drugs.com and read about all of them available where you are.

There are some antidepressants with a lower risk of sexual dysfunction. Examples include: bupropion, mirtazapine, and vortioxetine. It’s worth emphasizing that any change in therapy should be done under a doctor’s supervision, as others can have a higher risk of other side effects or the possibility of affecting other drugs a person is taking.
