The games might not be as loose as you thought they were, they just might have been going through a loose phase. Additionally, you have entered the game, which reduces the number of players to the flop two ways. First, you don't see the flop as often, and secondly, if you are raising preflop, you eliminate the chance for other people to see the flop cheaply, and unless they are complete maniacs, most players see less flops for two bets than for one.
