I reject the premise of your question. As of writing, on the front page of Off Topic discussion there is an avatar thread, a poll on TV series finales, 2 threads related to the 'raise money for Allison-fromExtra-Credits' Shoulder surgery drive (Which you should totally donate to, btw) a Lulzsec thread etc. etc. There is only 1 'gay' thread on the front page. Namely "What's with all the gay threads lately?". In fact your thread is the only one related to homosexuality on the first three pages of Off Topic discussion.
Okay fair enough, but what about the Religion and politics section? Well again there is only one thread about homosexuality on the front page, and it's by someone decrying that Liberals somehow don't "Allow" him to hate gays. On the second page there are three. All of which are related to current events and headline news items, namely NYC's gay marriage bill and Chicago Pride. Searching backwards we find one on page three and one on page 4.
Hardly overexposure.
It really peeves me when people automatically have this kneejerk reaction to homosexuality as 'innapropriate'. It's one of the more insidious forms of homophobia. A light peck will get a "Oh, I fully support your right to love whomever you wish, but could you not kiss your partner where my children could see? It's innapropriate" meanwhile the straight couple full on snogging up against a lamp post hardly get a mention. "Oh, could you not mention this extremely historic and ground breaking news item quite so much in my gaming forum? It's innapropriate" Never mind that on the first page of the Religion and Politics forum there's a poll asking when it's okay to hit a woman with one of the possible answers being "When she burns your dinner", and a thread about forced female circumcision.
It really gets my goat, is all. You want innapropriate for this forum? How about trying to impose your idea of what topics should be discussed in a free, public forum specifically designated as a place where people can talk about whatever they bloody well want?
