Has Luvox lowered my libido or is it all in my head?

I feel like Luvox may have lowered my libido a tiny bit, but I also feel like it may all be in my head cause I worried a lot about it when I saw this as a possible side effect. I feel like I may not have noticed anything if I had never read that. Plus, I used to be on Prozac and never noticed anything. Also, I read on Wikipedia that Luvox commonly has less sexual side effects than other SSRIs. What are your thoughts? Thanks so much in advance!!
