I Have Bisexual Desires

A few days ago I was in the local shopping centre killing time on my own simply browsing around various shops as I often do when taking the wife shopping for the day. We go fairly regularly she goes of to the usual M&S or Debenhams etc while I take a walk around and look at electrical stores or some clothes shops. I happened to be in the HMV store browsing through the dvd's, when I noticed a slim handsome grey haired guy probably around my age at the next row over and I think that's when I realised my bisexual desires are becoming more prolific. He was wearing a very short pair of shorts, like those you would wear for running and a sporty anorak/showerproof jacket which reached halfway down his shorts. I was quite drawn to his stature and sporty looking legs and in my mind I wanted to go over to him and say I like your shorts and you look very fit. What am I thinking ! goodness he might be gay and appreciate the compliment then what happens what do I say ?. Then he might be in a similar frame of mind as me or he might just be enjoying wearing very shorts shorts and tell me to p*ss off, isn't this confusing !.
I have never found a guy attractive before but I so wanted to say hello and strike up a conversation. Alas I never did but my mind raced on about how the conversation may have gone, it felt exciting and as I left the store I wanted to kick myself for not initiating a conversation.
It seems like my bi-curiosity desires are coming more and more to the forefront. Maybe one day I will have the courage to say to a stranger Heh I like you in shorts you look good in them.
