I used to be like that. When I was in my teens and 20s I usually hooked up with fellow students around my own age. Although I let older guys fuck me in the cruising park my focus was on guys my age as potential boyfriends. But getting fucked first and only acquainted after that didn't really work getting a bf 😉 More like getting regular fuckbuddies to go home with when the lights were turned on when the club was closing and everyone still there was looking to get laid. Plenty of guys I had sex with before and knew I was "easy".Maybe I was too slutty to be boyfriend material LOL.
In my 30s I also liked men around my age. Didn't really look at younger guys, and certainly not a lot older. Although I still got fucked by older men at the park.
When I hit my 40s I found not many men were looking for a 40s bottom. I was still looking at my own age group. Got a lot of replies from tops they were looking for younger. Still got plenty but I found it harder to find hookups.
Then I turned 50 and thought my days were over. Who wants a 50s bottom? Well, it turned out a lot of guys in their 20s and 30s do. I apparently turned "daddy" and plenty of younger guys were up for that and I happily went for the ride. Never knew these guys existed. Wasn't looking at other 50s guys anymore but focused on the younger ones.
Now I have a few regulars who are all younger than me, ranging from 20s to early 40s, who want to fuck daddy's ass and I love it. I don't exclude guys my own age or older but I find I really need to be attracted to them. That means I want a face pic and some information before meeting (and they are usually in a relationship or come as a couple) whereas I would invite a 20s or 30s guy over based on his dick pic 😉
I do realise I would be at a disadvantage in a bathhouse setting (there aren't any around here but I do know them from my earlier days) where there probably is so much competition from younger bottoms with willing boy butts I don't stand a chance. But I can't complain having what I have now and enjoy it while it lasts.
