First gay experience

Yesterday I had my first gay experience. It all started with me searching on X hamster explaining that my girlfriend regularly sticks her finger into my bum and I entertained the idea of having something bigger and longer in there. Which of course would be a male 2 male situation. It did not take long and somebody replied: "Yes I could make you happy" we send several messages to each other and it quickly became clear that it must be very discreet. As I live alone, that was no problem ( My girlfriend comes over at night ) So we exchanged phone numbers and my address was given over the phone. We made out a time to meet, after lunch. He was right on time and he seemed very forward, suggesting to watch a porn movie. So I put on a gay movie to show him what I like. It did not take him long and his pants were down, I admired his cock as he slowly stroked it. He had a good looking cock, so I touched my first cock, stroked it and it felt nice, not being too shy I put my mouth over it and started sucking on it, taking him all the way in right down my throat. He started to moan slightly and I knew I was on the right track. His cock got harder, then he stood up and put my cock against his, rubbing our mushrooms together. We docked together and our heads became one, which nearly made me cum. But I did not want to cum yet, so I suggested to go to the bedroom to which he eagerly agreed, the rest of our clothes came off and I sucked his cock again. He put some cream on my bum and I knew it is finally going to happen. He pushed me on my back, I lifted my legs up and he had his cock right in front of my bum, slowly trying to enter me: "oh you are so tight" he said "Yes, you are the first one" I replied,so he tries again and his mushroom enters me, he pushes deeper all the way in. Now I start moaning as he goes in and out. Finally I am getting laid. He strokes my cock while he is fucking me. In and out it goes, he has great stamina but i feel him getting wilder and soon he shoots his load into me, which is too much for me and I cum too. He goes to the bathroom and I lay back thinking about what happened, my legs are shaking uncontrollably as I try to regain my senses. I know this will be an unforgettable experience.
Today I am still sore, but what a wonderful experience, whenever I think about it (nearly all the time) my cock gets hard.
I messaged him and told him he can have me any time now and would like to explore more possibilities, especially getting our cocks docking together, as one again.
At my age 73, I am now open to all kinds of scenarios, but nothing violent.
