Question about a male friend?

I have a male friend on MySpace (he was my co-worker 10 years ago, then we became friends again online some years later). Anyhow, here is my question: He has a lot of female friends (platonic), including myself. He sends and returns kisses to them on the "Kiss Me" applications all the time, as well as the "Hug Me" applications. He will accept "hugs" from me all the time on there, but never approves my "kisses" from the Kiss Me application. Yet his other female friends, he not only accepts those virtual "kisses", but returns the favor. Why am I always left out of the loop? Is it because he finds me unattractive? (Many people tell me I'm beautiful, and I'm his #2 friend on MySpace, out of about 170 people). Please help me delve into his mind...
