Oh yeah, mine definitely went up.  Big time.  I can't remember exactly how much but it was a major shock.  I'm also under 25, so in two years it will go down.  Something magic must happen I suppose.  Perhaps the cautious driver fairy will sprinkle safety powder on me for my birthday.
Totally kidding about that.  I just find it ridiculous that males under 25 pay significantly higher because of statistics.  I'm the safest and most cautious driver I know besides my mom.  People hate riding with me.
Good thing yours will decrease.  Older than 25 I suppose (30ish maybe)?
