Hair is a huge, huge factor. I've had extensive laser hair removal and I have very little smell in general. I *think* my scent has changed some since I got on spiro, but it's hard to say.
If you don't like the way something smells, shave/wax/laser it and wash it every day see how that goes. Scent really is a sexual factor though. I am not a big fan of the down below on women anymore, but the scent of the armpit is actually something I've really liked on women dating back to my first relationship. My ex and I caught a Discovery special about attraction and it covered how important the armpits can be. Though, yes, it's weird to go sniffing under your partner's arm for arousal.
For genitals, cotton underwear certainly helps more than microfiber or nylon. It's much more breathable.
It's weird, but, I actually used to really like the way I smelled below as a teenager... I don't smell that way anymore. I guess I could go find a boy who does.
I don't understand why we evolved the fishy smell, it's really not attractive. Maybe primitive humans used women as scent traps to catch animals or something.
