I know of many women (me included) who were extremely hypersexual to the point of struggling to sleep due to sexual frustration while pregnant.

I can definitly see how crazy hormones, plus a considerable lack of sex can equal crazy making sexual frustration.

My 2c? Don't be too quick to pathologize it, its unpleasant enough as is.

Although, if you are experiencing any additional manic symptoms, well then maybe its a bipolar thing rearing its head afterall.

To which I have no solution as sex and meds are both no-no's...

Distraction is the only tool that comes to mind.

Goodluck!
