I agree with @JG24FanUK - if you don't like the taste of your vagina, then no, don't do it. If, on the other hand, it has nothing to do with the taste of your vagina, then why not. There's nothing unsanitary about it.
I would venture out and say that a lot of guys are interested in this. Every single one I've ever been with has asked for this. I got to the point where I made the rule that if I had to taste myself, so did he - though I've never hated the taste of my vagina. If I could, I would probably get down and dirty with my bad self orally, but I can't, so I won't.
Your definitely not making a big deal out of this, but I'd say, don't knock it until you try it, because you never know for sure if you like it or not if you don't. And it's all about personal preference - if you don't want to try it, don't. It's your body, your mouth, your decision completely!
