I sweat big time on long rides and usually end up with a salt covered crust over everything. What works for me is Gleukos. It isn't sweet at all, just like light lemon flavored water and comes in a powder so you can add to your water when you feel you need it. I also use Endurolyte tabs.

Don't know about it being a female thing, I think it just depends on the person.
DH sweats, but doesn't get the salty crust. One of my other riding buddies sweats like I do and we compare salt markings at the end of our rides. He is an ironman with very very little body fat. Other riding buddy rarely sweats at all.
