why does josei smut sexualize women more than men

i read male gaze hentai, i see detailed drawings of fully naked girls blushing crossing their eyes screaming out and everything. they barely show the guy and if they do he's always fully clothed and expressionless

im like "ah makes sense this is for straight guys" i try reading smut written by straight women thinking it would be the complete opposite. its literally the same thing. they dont even bother drawing men's nipples

like im not some porn addict but it makes me super confused. do women just not find men's bodies attractive? they have no problem sexualizing men in yaoi so why not in straight romance?
