When younger I would always dig (What I called) "ego trips", which means I'd hook up, and then let go. Guys do this sh!t all the time! Unless you 'want' to get close to someone, chances are that you'll ditch them eventually. It's just human nature, man!

When you connect, you connect! It's that simple!

Until then, "enjoy" yourself, and don't worry about it!

Just my two cents,
