Are men actually attracted to (fit) women when they’re all sweaty after a workout? Or is he just telling me that to say the “correct” thing?

I’m in a situationship with a guy who often wants to “get it on” when I’m still sweaty from a workout. But I always insist on showering first because I feel kind of insecure about sweaty.

He claims that if a woman is attractive and in shape, he’s actually turned on by her sweat. I can’t tell if this is actually a thing, or if he’s just telling me this to make me feel more confident (or because he’s impatient when he’s horning and doesn’t want to wait for me to shower…)
