Finding Out Its Amazing

More out of jokingly saying it, I let my neighbours nineteen year old son know I'd fuck the crack of dawn, if I could get up early enough. The reason I'd said it, was because my wife and I hadn't had sex in over two years.
His response was "You can fuck me anytime you want".
I knew he was gay, but being in my fifties and straight, I never thought for one minute I'd fuck a guy, or that someone his age would want an older man to have sex with him.
It didn't stop me getting a hard on, or him noticing it. So he said very matter of factly "Your wife's out, why not fuck me now".
It was a half hour that has changed my life. Not only did he suck my cock until I was desperate to fuck him, he also had me tongue his arsehole. Something I thought I couldn't ever do. Yet there I was after tonguing his hole, pushing my bare cock up his arse from behind on our couch.
And I loved it from the word go.
It was utterly amazing. So sexual and so damn horny. Plus he wanted fucking just as much as I wanted to empty my balls.
It wasn't our best fuck, but it was good enough to have him cumming on our couch, and me busting my nut deep inside his arsehole.
Like it was just an everyday thing, once I'd pulled out of his arsehole, he kissed me, got himself dressed and said "Anytime you want to fuck me ***, text me".
We exchanged numbers and the very next day with his parents at work and my wife out shopping, I spent two glorious hours kissing, stroking, rimming, sucking, being sucked and fucking with J.
We fucked three times and by the time I'd cum up his arsehole the last time, I was a fully fledged bisexual man.
Everything was an experience I enjoyed and given how into me J was, I quickly realised the age gap between males didn't matter. In fact he was so horny for me, J wanted to us to shower and fuck again. Unfortunately my wife text and asked me to pick her up.
It's been just over nine months since my introduction to gay sex, and J is no longer my only sex buddy.
I've also begun fucking a young guy (20's) who I work with. He doesn't want anyone to know he likes older cock (He has a girlfriend), so we occasionally fuck in my car. However he's into fishing like me, so we've recently been having sex in the tent I go overnight fishing with.
J introduced me to gay sex and anytime he wants my dick, I'll fuck him. But I'm not going to stop enjoying other young men from now on, especially as my wife has absolutely no interest in sex anymore.
