As a fairly typical westerner, I can assure you that nobody - nobody - can pick out the smell of my dick from a foot away, even if I've been exercising, even if I'm gettin' intimate, even if the wind is behind me, shit even if I haven't bathed in a day or two. Yeah, its 100% true that men and women have manly and womanly scents, and that you're gonna experience them in sex, but they don't come out in stink waves from otherwise clean bodies or overpower normal human smell through your clothes. If you believed the way manga are written, you'd think the average crotch scent was on the same power level as a middle school boy's AXE body spray dosage.
