As far as I know, none of the cycling-specific products are scented. They're meant to be used down there, and cyclists being pretty close to each other when they ride, I'm sure no one would like the cyclist behind him/her to smell what kind of chamois cream they're using. "Oh, is that Chanel #10 Chamois cream?"

I've used zinc cream just like that used to prevent diaper rash (quite cheap) in multi-days rides with very hot and humid weather when my skin would go raw because the chamois couldn't evacuate the sweat anymore. Not sure what it would do for more intimate irritation, though, I was just hurting at the crease of the leg. Anyway, the stuff was white (as you know if you have a baby) and washed out perfectly. I always turn my shorts inside out when I wash them, no matter the circumstances in which they were worn. I kind of imagine vaseline as being more pleasant to apply, and less likely to leave marks on the OUTSIDE of your shorts!
