If you are married is it ok to have close friends of the opposite ?

I have been happily married for 11 years to my best fiend and hopefully my lifelong companion, but I have always had more woman friends then guy friends. And no i am not feminine in any way, shape or form. Yes, I am in touch with my feminine side but believe me I do guy things and am not interested in sissy stuff. I just prefer conversing with women alot more than men. I do like to flirt but if it ever goes beyond that on her side I feel very uncomfortable like if I was propositioned the same . LOL Anyhow i continue to have many women friends and want only that froom them.
