Why do people call me a 'perv'?

I watched countdown as I do often, and commented on the girl who picks the numbers saying she has y legs, and I get called a perv? What the hell, I'm not allowed to express my heterouality anymore, oh no that's dirty, that's perverted, heteroual men are perverts. Would you prefer if I commented on Jeff Stellin's legs? Why do girls often pull out the 'perv' card, especially as girls often comment on the opposite just the same. No wonder many teenage boys are confused on how to express themselves, they think their uality is tainted, dirty, perverted and unnatural..
