SSRIs destroy sexual function but not all anti-depressants do. In particular, if you are hypomanic, SSRIs won’t work on your depression anyway. Drugs for hypomania do not impair sexual function and will definitely increase it if you have hypomania. Depression is certainly the most common cause of male loss of libido. Hypomanics are often misdiagnosed because the differences with vanilla depression are very subtle, but the treatment is completely different.
