Why do straight women love bromance?

I have been watching Queer As Folk and it is one of my all time favorite TV series, and I also watched a lot of films and fictions depicting homosexual love. Clearly I am not the only straight girl who find herself standing awkwardly in the "gay world". It is kind of a "queer" phenomenon and I sometimes can not help asking myself this question--why do some heterosexual women, like me, love bromance so much?

Every time when I get excited about bromance I try hard to find a reason for my weird and "straight" love towards gay men; although at first I didn't think it make any sense at all. But there must be some reasons lying behind it, especially when it seems so unnatural. In order to justify my behavior, first I cut bromance into two essential elements: two men and their love.

It is easy to account for the "love" part: every one seeks for love, and love is the forever topic in  art works. But how the love of heterosexual people different from that of straight individuals? I guess what is lying there is that gay people often face more obstacles in their journey to love. The pressure and responsibility from society and family block the love between same sex, but also enrich it with mind-shaking struggles and heart-moving loyalty, which is even amplified in films and art. This is what strikes straight women and raises their sympathies--the bold and unlimited  love.

But why does it have to be two men? We can not deny that lesbians as well as a few straight couples encounter the same amount of pressure from society. My account for this is their sex orientation and the boredom of stereotype in a traditional heterosexual relationship. The first part explains why love of lesbians fails to attract straight women; although it may not apply to all the cases.(I watch lesbian movies and whatnot as well, probably because I unconsciously want to be "fair") When it comes to straight couples,  I guess it is the unchanging relationship that is losing the audience. Some women hate to be portrayed as weak, emotional and delicate; and this is sadly still the norm in literature and film industry. Whenever in a book or a movie I see a dependant and helpless girl crying and complaining I just cannot help letting out a sigh. This is why generally a "moving" love of straight couples can hardly evoke my empathy to the same level as an equal relationship between gay men does, which is ironic when I realise that I am technically still straight.
