Strange, but given that they engage in the same level of promiscuity, Matty receives more condemnation than Eric. Lots of finger-wagging and hand-wringing about him settling down and how he'd warp poor Chuck. Thing is, we should have known all along that Matty wouldn't harm Chuck from how he treated Twoey. In both cases, he practices what Dan Savage called the "public park rule" -- always leave a person better than how you found them. As the more experienced guy, he's a patient guide, even going so far as to care for Twoey after Eric date raped him. Sure he's a slut, but he's an ethical and principled slut (even if his moral code is unlike ours). Given the parallels between Eric and Matty, I am much more worried for Twoey. Mattie builds Chuck up; Eric is going to tear Twoey apart, whether it's his intent or not. Mattie and Chuck are not boyfriends, and are not monogamous, but their relationship is actually pretty healthy. Eric and Twoey are exclusive (and out, no less), but this is far from healthy. Maybe we put too much stock in monogamy, leading to some getting into, or staying in, relationships that do them more harm than good just because that's the expectation. DOWN WITH TWOIC! DOWN WITH DAVEX!
