Newsflash my virgin friend. Girls are as dirty or even dirtier than guys. Asking a girl to shower first before sex is laughable. Meet any chick at a club, grocery store, library etc... and she probably has picked her nose, farted on her way there, scratched her dirty ass beneath her closed and never washed her hands once.
my friend that is a given,
but knowing that the 30 grimmy dudes that got lap dances before mixed their germs with her sweat and now she wants to rub that sweat on you is a turn off.... that is just me.
There is nothing wrong with asking a girl to shower you..try it, you might like it
