Cowboy Bebop has a surprising amount of this between Faye and Ed, ranging from Ed affectionately calling her "Faye-fairy" (cute, but relatively innocuous) to Faye kissing Ed on the mouth in a very weird attempt to wake someone up.
Don't forget Faye's super manipulative behavior towards Ed, is Ed that crazy to believe Faye, or is Ed...
Can't analyze Cowboy Bebop's Ho Yay without mentioning Grencia/Vicious. Or 'Gren', as Vicious called him. It's even more visible if you have in mind that Grencia tells Faye that he is not interested in women, twice.
There's quite a bit of this implied in the Spike/Vicious/Julia backstory as well.
