Well firstly, I want to thank you for not being concerned about your man card or feeling gay or whatever, which is what I feared upon seeing the thread title.
(Edit: D'oh! iTunes! I forgot. How embarrassing. Yeah, just buy from iTunes if you're that worried about it.)
As for your question, keep in mind that Hasbro doesn't really care about the show itself because the company makes the vast bulk of its money from merchandise sales. So buying some official merch if you like the show (they have some nice shirts over at We Love Fine) would make them perfectly happy. Also the actual PEOPLE who make the show love the community and are really just happy to have so many fans.
There are a couple dvd releases, but they're not very good. Specifically they only have a few episodes (and not the best ones either, IMO) and no extra features. I also believe the latest episode is usually available on the official website a few days after airing, but that doesn't really help to see the full series.
And if you do take a liking to it, I feel I should point out that we have a rather large user group here on the Escapist:
