It's not really abnormal...
Assuming they've both got the exact same setup, you've most likely just got a very active male and a very lazy female. And an '09 male probably just got hit with his first real burst of hormones, and is suddenly mad to breed. Is he producing sperm plugs yet?
Give him a cardboard tube to cuddle with and tell him it's tough all around.
EDITED TO ADD: Yeah, sure, those warm side temps could use an extra 5-10 degrees. Though I doubt that's what's causing extra activity from just the male.
