My dead fish analogy is making rounds, I see I seeOh dahling, Daigo Atsushi has always been infamous for being a dead fish.
There are actors who deliver & others who don't. But then again it really depends on your taste. Are you like looking only for the muscular bodybuilder type like Daigo Atsushi or can it be of any other type?
Some of the actors (not necessarily my favorite) who look OR act like they're enjoying gay sex, in no particular order, that I can think of right now:
Takimoto Ryota (瀧本涼太).
Sakurai Yuya (桜井結也).
Hanzo Saji (左慈半造).
Frankfurt Hayashi (フランクフルト林).
Chitose Koume (千歳小梅).
Sakurao (桜男).
Nagasaka Kodai (長坂輝大).
Takuto (タクト).
Or here's a post with a list of my faves but not necessarily what you're looking for.
