Just what I needed

Let me start this by saying this is 100% a true story. Im using this an outlet for reminiscence, unfortunately the guy wouldn't let me record it and so I thought I'd write it out while it's still fresh in my memory. 

So I'm a 24 year old guy, I have a girlfriend and no one knows I like sex with men. I'm sort of bisexual but I don't see men in any kind of romantic way, I just have certain strong desires that I keep to myself. It's been like this since my early teens but the desires have gotten a lot stronger over the years and definitely dirtier. I had desires of being a submissive bottom.

I've always been extremely nervous about meeting guys, so I would usually just watch gay porn or masturbate to the thoughts in my head. When I was 20 and recovering from a bad break up I finally got the courage to meet someone. I was on MDMA with a friend and he was staying over at my house. While we were watching tv I told him I was going for a walk, but I was actually heading to someones house who I'd met on Grindr. I was ridiculously nervous but I just did it. It was my first time and it was quite good. I sacked his cock, he fucked me in a few positions and it was a good first time. A few months ago I met someone else and it was really bad. He had a tiny cock but I really didn't mind that, but he wasnt dominant at all, it was really boring and I was putting in a hell of a lot more effort than he was. 

-Sorry if I'm rambling, I just want the full picture of how significant this experience was for me.-

Fast forward to a few days ago, I had some drinks with my friends and went up to bed early, a little drunk but not that bad. First thing I planned on doing was having a wank to some gay porn, but lately I've been really underwhelmed by porn. I couldn't find anything that depicted my fantasies, except in straight porn. So I decided to go on Grindr and the plan was to just speak to someone, dirty talk, exchange some pics etc. I got speaking to a man who was 52 years old, which for the record is a big turn on for me. We both spoke about what we were into and stuff and exchanged a few pictures. I told him exactly what I wanted and he loved the idea (I'll get to that soon). After a few more drinks by myself and talking to this guy he asked if I wanted to meet up. It was around 1AM but I thought fuck it
