An odd thought while I was getting blown

I met up last night with this 25 year old Mexican twink for some oral.  He's 5'7, 140 pounds and medium complexion.  He asks me if I want to watch some porn and he puts something on but I never actually watched it.  He say to me anytime you want to start.  I start undoing my pants and gets this excited look on his face.  I decide that I want to take the action to him and fuck his mouth instead of lying back and letting him do the work.  So I get off the couch and undo my pants and let it all go down to my boots.  He goes in and inhales my cock.  I start pumping his face full of my cock.  He did okay considering I pretty much just skull fucked him for about 20 minutes.  He was a little toothy on the blow job but I did force the issue when he would try to take a little break, I would jam it back down his throat.  As I was getting ready to cum, I made sure my cock was deep down his throat so he wouldn't waste it. I didn't ask and he didn't object.  But right after I came, I started thinking about how eager this 25 year old was swallow my cum and how different it was when I was his age.  Back in the mid 90's when I turned 25, I didn't know anyone that swallowed.  It wasn't until much later that I had someone swallow.  And I remember it like it was yesterday.  It turned me on so much.  I think it might have something to do with the era in which I came out and the safe sex message that was drilled in everyone's head.  It seems like guys are much more at ease with it now.  While you can call me a hipocrit because I want to shoot my load inside whether it's a mouth or an ass, but I don't let a guy cum in my mouth and on the rare occasion that I bottom, I use condoms.  I thought it was a strange thought to have as a dude is slurping the last of your nut out.
