Hello I Was Prescribed Paxil 12.5 Mg From My GYN

Hello I was prescribed Paxil 12.5 mg from my GYN . I do not have depression! I only complained about Hot flashes severely . I have been taxing the Paxil for a month and half. My problem is I am very sexual WITH MY HUSBAND and I am experiencing trouble having an orgasm. Is ther a solution for that? Perhaps another medication? Also after reading other people comments i AM SCARED I could have bad other side effects from this drug . Is Paxil addictive and will my dose age have to keep going up and if I were to quit taking it have withdrawal???? Does it cause weight gain????
