Unfortunately sexual side effects are common with SSRI's, and its effect is different for individuals, so really it's probably a bit of trial and error. Also i should point out that these are commonly used these days because they are effective for treating depression... which is a priority...sometimes you might have side effects from SSRI's in the beginning, however these often subside once your body adjusts to it... sometimes it is just worth the trade off and patience is necessary
However... if this is a real concern... the older style of antidepressants (called tricyclics) can be very effective and have fewer sexual side effects, however they are not as commonly used (one reason is that they are more dangerous in an overdose).
Another antidepressant that you might want to discuss with your Dr is a noradrenergic and specific serotonergic antidepressant (NaSSAs)- there are only two of these on the market at the moment: one is called mirtazapine, and this is known to have few/ no sexual side effects.
I hope this helps in some way.
