I was just married and I was proscribed to generic celexa(citalopram)20mg to be taken every day for a stress disorder.I never have been prescribed to any antidepressant and I cannot take anti anxiety meds(zanax,valium ect.) because im allergic.I need to know if it often causes you to have less of a sex drive or make intercourse less enjoyable.I read 1 persons post before that said it had a negative effect on sex drive &performance... any thoughts?
