Raising the turn (non-donkbet) with my aces

[Ortho]

When I raised the turn here, I got a little tingle in my stomach like when you're on the rollercoaster. I want to make sure that this isn't spewing, because I could quickly become addicted.

I've been in a number of pots with villain, and he's loose-aggressive. He's very aggressive postflop. Also, I've open-raised two or three times in the past orbit but haven't shown anything down, so he doesn't necessarily think I have anything.

I think these factors argue for the turn raise, but is it standard? Would you do this against an unknown? I typically just call here but I think that I've been missing bets. I'm considering making this turn raise/call down after 3-bet my standard play and would like opinions.
