Celexa will definitely cause low libido......my wife is on it and getting her going is harder than starting an old Ford pickup in winter time..

Wellbutrin works on another area of the brain....alone it doesnt have the sexual side effects of the newer SSRI's

but if your still taking Celexa im not sure what good the Wellbutrin will do to help...

I take 20 mg Celexa and 300 mg Wellbutrin....I cant orgasm and some decreased libido

hope this helps
