Walking around town as a tourist is a good excuse to check out the local hotties. Which I attempted to do as much as possible without being obvious. Or too obvious, anyway. Which led me to the following observation (personal development alert): my sexual preference is really quite agile.
I used to think I had phases. Maybe it was part of the denial process, but for a period of two years I had a clear preference for women. Before that, men for a while even though I fiercely repressed it. I know I always had that gay part in me, I can even remember innocent indicators of it from my childhood. I know I didn't change to become this way, I have always been like this. But I'm still discovering myself, because I've set my mind free.
In Spain I noticed my eyes occasionally jumped from hot guy to sexy girl. This is new to me, but I like it.
