Not all people with Bipolar disorder have the "stereotypical" wild sexual appetites that have been listed under criteria for Bipolar, but in many,not all can occur. I have been always been the opposite, little to no sex drive.
So I do not feel all Bipolars have super sex drives but can too, maybe your meds will nix this problem, maybe just getting on a mood stabilizer and getting balance in your life will cool but not kill you appetite, it's a matter of getting on a treatment plan with your pdoc and with medication/mood stabilizer and any other med combos.
Just my 2 cents. I wish you luck with this, my oldest brother is on his 3rd marriage and it's working, he is Bipolar-I, was DXed and put on meds back in the late 60's, had rough years in the begining but has been doing fine for years. So don't give up hope.
Please take care now,
