Should I Try

Hi my names Carl I am a married gentleman of 55 who has been married to a woman for 26 years, but wonder if I’m closeted bisexual.
Now I wonder if I’ve always been bi , why because of experiences that happened when I was younger . At 19 while in college one of the guys was from Holland and was not ashamed of his body and would walk around naked. One evening this happened when only the two of us were home & I found myself looking at his penis . Obviously he caught me looking which caused him to become hard, which in turn caused me to be aroused, which I’m sure Joseph saw because he ended up sitting right next to me and taking my hand and placing it on his penis. Now I now it was wrong and I must have been interested because my hand actually encircled his penis before snatching my hand away( where we all know that one I should have pulled my hand away and two it would not have actually encircled his penis if I was not kind of interested) This did happen on two other occasions & I think each time I encircled his penis and held it a little longer each time before snatching my hand away. Need to say nothing actually happened after the third time & it never happened again.
Now moving on a few years in my mid twenties I caught a gentleman in a local park masturbating to a porn magazine & ended up spying upon him actually doing the same thing. I will admit I went there looking each time about 6-7 times. But on the last time he actually caught me & we ended up coming closer together and actually masturbating together watching one another . Again nothing more happened & after the encounter I never saw him again.
Jump forwards to where I was 42 and in Paris for work ,,& one afternoon found an adult cinema ( never ever going to one before I decided I would go check it out)
Anyway it was hetro porn but it seemed single men were solo masturbating but a few were also mutually masturbating one another.
Again those old feelings came back and after a short while I unzipped and joined in . Again watching the film and also the guys around me .after a while an older man sat next to me and whispered to me in French “ was I enjoying myself, or did I need a little help ( I guess he had seen me not only watching the movie but watching the other guys too) for some reason I nodded to his question & he took my hand from my cock and started wanking me himself. After a little while he also got his own cock out and began to wank it with his free hand . After a while he must have also seen me looking at him wanking because he nodded his head towards his lap and I took it as a sign he wanted me to wank him too. Thus my first mutual cock wank happened (?& yes you may have guessed I was naughty because yes I was married, well I still am)
But during that time my mind did have homosexual thoughts, what would happen if he wanted to suck me , I knew I would suck him back , but my mind also went to that scene of him buggering me & the thought shocked me because it did not turn me off.
Needless to say none of that happened but we did both make each other cum and we left without a word.
Since that time I started watching bi porn, but that turned to gay porn because I found that actually turned me on more yes even with the kissing .
So now my mind is wondering now I’m in my 50’s should I actually try gay sex . Should I go to a gay sauna, tell someone there if someone interested that I’m straight curious & would actually like to try bottoming at least once because I’m now sexually confused .
