I'm pretty sure you have a yeast infection. Those itch like crazy...and any guy who laughs about it, sayin' crap like "scratch it" or "gross", I hope they get on on their dick, cuz they won't be laughing then.
Ok, so, girl, you need to tell your mom. Yeast infections
occur because there is an imbalance in the bacteria. Tons of things can cause it: Don't worry about telling your mom ~ I don't know a woman who hasn't had at least one.
