"i have been taking citalopram for about 6 months. it has helped me with my depression bit i seem to have a reduced sex drive and am unable to orgasm and get a headache before i orgasm. my lover can&#039;t stand this and thinks it is her fault (not good enough). i have no problems getting an erection and keeping one. just have a problem reaching orgasm. plus the head pain is bad taking the pleasure away."
