Showering before Sex

I do wonder how people can do any sexual activity without well cleaning like showering right before that. I do have a good hygiene but still tend to sweat a lot and I know I don't smell well already one hour after the shower. I'd never ask a girl to go down on me without good cleaning first. Similarly I find the smell of a sweaty vagina not plesanat at all. Am I the only one with this idea? I've been wondering this for years Any comments welcome
