I get a similar thing, i get it after around 30 minutes and it feels like i got nothing down there! I might adjust my seat down when i get a new one .

No doubt! Get yourself some nice cycling specific shorts and feel the difference. Now, you don't have to go blow your paycheck on a pair, but a really nice pair will go a long way in terms of comfort. I know there is a women's forum section somewhere around here, so hop in there and get some feedback.

If you don't already know about the women's section, pm Koffee Brown for entrance. She'll show you the secret handshake and everything!

I never get numb on the crotch but have occasionally on the fingers. But...by moving the seat down a bit to more even with the bars, you are not leaning into the bars, thus not numbing your fingers. I would think the same holds true with seat. If you seat is pointing down, then your butt is sliding always downwards...thus putting pressure on your crotch,...numbing the little goodies down there.

Might just try adjusting the seat....

Buy a pair of bike shorts with a cushy chamois. I have a Pearl Izumi pair and they are worth every penny. If you are riding 12 miles daily you'll need bike shorts eventually since they make a world of difference on your sensitive bits. Make sure you go commando underneath them though, underwear is not recommended. They wick away moisture and have an anti bacterial lining, since you don't want an infection and numbness!
