The Future of Sex: It Gets Better

As a hobbyist adult mango artist, I have to agree, the internet has done wonders for sex. And, as a ME/CS engineer, I would really like to be able to be at the forefront of further advances in the field of robotics...

But all hype and optimism aside, why is there no medication for female sexual dysfunction? I'm trying to come up reason by looking at this from various perspectives, but nothing seems to make much sense. From a religious point of view, reproduction in a marriage is important, so it'd make sense if the female is sexually interested. From an economic point of view, developing a drug that solves a market need is worth tons of money (also no competition). From a feminist point of view, a woman's body, including her sex, should be her own and any dysfunctions she should be entitled to fix. From a misogynist's point of view, sex is one of the things a woman is good for, so it makes sense you can have it with her.

So why is there no drug for female sexual dysfunction? Is it really difficult technically or something?
