I have this problem, but I am also in a mixed state right now. I want to die one minutes and then I am on the phone with someone I shouldn't be having a conversation that isn't appropriate. The problem with being bipolar and going through the hyper sex drive is that you are usually feeling manic (or somewhat manic) and you want to feel everything and everybody around you. It's like you are on a huge mountaintop and you think everyone wants you. Unfortuantely, you can find that someone that totally wants to give you want you desire. That's when the problems begin....
I am speaking from experience that being hypersexual is not just a crazy sex drive or just ovulation. Of course it is true that ovulation increases a woman's libido, but watch out for a bipolar that's manic/mixed AND ovulating!!! This has been a hard road for me personally and I hope that you find the info you are looking for. Bipolar Magazine did a cover story on this subject about 6 months ago. If you can find a copy, I highly suggest it. It will give you more insight into hypersexuality and be a great resource to show your husband. I must confess that I have never discussed this with my husband as I have a lot of guilt that goes along with this part of BPD, but kudos to you for facing it head on!
