Is Felix Gaeta Gay?

Paul Florez in The Advocate wonders if Lt. Felix Gaeta's big secret is being gay, and being in love with Dr. Gaius Baltar?

Actually, we know from Ron Moore that a big secret between Baltar and Gaeta had to do with a massacre of Sagittarions on New Caprica. A story line that was subsequently dropped. However, gay characters seem oddly absent on BSG. Does the Colonial military have Don't Ask Don't Tell or something?
