The loosey is to MY immediate left, so he has position on me 2 of ev 3 hands.

"First to act" is the advantageous position at this point*, since the first chips in the pot will often take it down. It's not like he's going to have position on you postflop, since all the money is going in beforehand.

* I wrote this backwards in my previous post. You definitely want to act before him though.
