Well that's a funny enough phrase that you could probably work on increasing the search volume for it. Regardless of what you end up using to monetize it, start out by making a matching youtube video for it.
Unless your planning to monetize the site with porn, just keep the youtube videos clean and simple. Maybe some videos of girls doing various things, shopping at a mall, playing tennis, walking the dog, rollerskating, whatever... you come in for a closeup and they get a frowny face say "my vagina hurts". Then at the end of the video close it with "Does your vagina hurt? If so visit MyVaginaHurts.com to finally get some relief." lol
If the live actor video is too hard for you to do yourself, then just do a scrolling text video. "When I'm out shopping too long, my vagina hurts. When I'm playing tennis all day, my vagina hurts. Sometimes when I'm on a long walk, my vagina hurts. Etc..." Then end the video the same way with "Does your vagina hurt? If so visit MyVaginaHurts.com to finally get some relief."
Then using the MyVaginaHurts youtube account search for other videos and just leave real comments, just so people will see you account name a lot. On some videos that will have similar vistors to what you'll be monetizing with actually leave a comment that will get them to check out your videos as well.
Do some real seo and backlink building so you're site will definitely rank #1, but it shouldn't take much to do that for such a low volume and I'm assuming low competition term.
What you really want to do though is get people thinking of the phrase. That way more people will start searching for it. So search out blogs and other places that are getting a lot of real comments that might be getting read and leave simple comments. Don't use myvaginahurts for the username and don't put in your homepage. You don't really need the backlink, just people getting the phrase in their minds. Basicall be an unaffiliated person making comments like "does any one know about this My Vagina Hurts place?" Enough people start seeing that and many of them will start doing the same thing.
If you try to promote the actual website MyVaginaHurts.com then you might not get as much interest because people will see it as marketing and be somewhat adblind toward it. By promoting the actual thought and phrase though you might have more success getting them to search for it themselves. Since you have the head start on it, your site will be the first result they find.
That's just an idea. Right now the domain isn't really worth anything. With noone searching for it and no real traffic coming to your site it isn't worth anything more than the standard domain fee. But, if you do something like I suggested and the search volume does go up, the traffic for the site will also go up and the domain will become more valuable whether you decide to sell it or keep it yourself.
It's something that would take time and might not always be worth screwing with, but for that particular phrase it might be fun to go around promoting it like that. It could be pretty funny. lol
Just brainstorming some thoughts for you.

Good luck. :cool2:
