I’ve had plenty of male friends before. I even fell in love with one and believe me – it was a shock to both of us. It didn’t work out, but we are still friends now and I don’t regret taking the chance on him (and I think/hope he feels the same way). If anything, I think it made us so close that really nothing can break the bond we have. No regrets.
(Oh and younggirls: if you do have something physical with that "special guy" and then he dumps you; he was always a pig, never your friend, and you're way better off without him. You can always tell your friends later that you dumped him because you discovered he has a small penis. ... no, I'm not talking about you, Paragraph 4 above girlfriend.)
