Unsure if normal or not

Back in high-school I had a guy friend and we would suck eachother off ever day after school. We would be in the room, go into my mom's RV, or in the back yard... we never made out or anything, and once we came we would just go back to playing video games or whatever.

Sometimes I think back to those days (I'm married now to my wife) and I've never been gay or bi with dating preferences, but every once in a while I just imagine his big dick in my mouth and I get super hard and just jack my dick off. Unsure if this is normal or if I should try to curb my thoughts, as it's still high-school him in my memories. I'm sure if I knew his last name (it's legit been a few decades) and if we hung out we miiiiiight still do it, even if he looks older or out of shape or whatever.

It's weird and has always bugged me that that's how I remember him, unfortunately. I don't look at anyone else in that same way (age wise) so I don't know if it's okay if I jack off to the memory or not.
