Gundam Wing 1x2 Fic

[Guest mmm_fluff]

So I'm looking for a 1x2 fic where Heero is doing a paper on something like the presence of homosexual tendancies in straight males. He asks Duo, his roommate to help him out by viewing pictures of like, two gay males, a male and a female and two females and then asking questions and stuff. In the end, they get it on and Duo asks Heero why exactly he thought he was straight in the first place. There's a similar sort of fic called Theory vs. Practical by the lovely ShenLong, but alas, this is not the fic I am looking for. If anyone at all could help me out it would be greatly appreciated.

hmmmm... went ahead and searched some more for you, the only fic coming up that matches is the one you already mentioned by ShenLong
