Takeshi Matsu is a Japanese mangaka, specializes in Bara comic. Bara comics are different from Yaoi, although they narrate men/men relationship. While Yaoi is meant for the female readers, Bara comics are written and for the male readers.
Matsu, like other Bara mangakas portray their figures as mascular and masculine looking males. Often the physique is over-portrayed, very much representing what the expectations of the general gay population.
