If enjoying part 2's designs and art makes me gay then I am ready to taste the rainbow. Is Araki gay or does he just really likes drawing jacked pretty dudes?It's both. Araki's pretty well-known for his homoerotic art style, but that doesn't not make Jojo the manliest shit.
From an artistic standpoint many people draw what they know, so naturally a man would understand the male body better than he would a woman's. Look at Boris Vallejo for example, yes he paints some extremely sexy women but his men are made out of God and Damn.
