Yes,a guy can hang out with a female & not have any sexual thoughts....it's rare,but it can be done.Let me give you an example,I have a friend at work & she's probally the best friend I have there.We talk a lot,we hang out,on Sundays we go to lunch together.That's it....there's nothing sexual whatsoever in my mind when we hang(ok,she's also 17 & that'd be like.....ewwwww,but that's beside the point).I look at her as if she were a sister that I never had.Now,maybe that's not the best example,but it is an example of how sex isn't always the driving force behind a guys thoughts....or at least mine anyways.
