bottle of wine works just as well.

I have never heard of female erectile dysfunction being a problem that the female would want to treat.  

Does this happen?

If not, "female viagra" is a pretty ludicrous notion

Addyi received FDA approval in roughly August 2015.  It's nickname is "female Viagra."  But it is a very different drug than Viagra.  Viagra, the "little blue pill," treats male erectile disfunction (ED), i.e., a male who has trouble getting a hard-on.  Manufactured by Sprout Pharmaceuticals, Addyi, the "little pink pill," treats hypoactive sexual desire disorder (HSDD), which is basically low desire for sex.  Lack of desire and lack of function are two very different things.  

During the FDA approval process, Addyi received a lot of flak for being moderately effective at best.  Also, it shouldn't be taken with alcohol and has potentially serious side effects (e.g., can impair liver function, cause low blood pressure or loss of consciousness).  Trials showed Addyi gave women who took it daily one extra sexually satisfying experience per month.  Not that impressive in my view.

I'd love to hear from anyone on the board who has experience with Addyi.  However, I'll be surprised if any of the ladies active on the board have much experience with it.  If you're suffering from HSDD, chances are you are not an escort.
