MWM confused

For the record, the image of the ONLY black cock I have ever sucked and that was 3 weeks ago ... but I want a local mature black man to orally service ... but this posting is about why it took 40 years for me to try this and does this make me bi, gay or confused

I have a serious question about sexuality and midlife crisis ... I have always been straight, never wanted to suck men but on a recent business I met an older black man at the hotel bar ... normal guy, well-built, strong workman's hands ... anyway, I got to my destination on a Sunday afternoon for a week long seminar that started Monday - I went to the bar to watch the football games and his mature black man sat down and we started chatting ... 3 hours and a dozen beers later, the topic of sex crept into our conversation and it was just regular talk about women ... then he said, "Why don't we got up to your room and you can suck my dick." ... I was shocked and applauded, he said sorry, just figured that no one would ever know and he thought that I would enjoy it ... I told him no way and walked away but he said, if you change you mind, I will be here for a while ... I went to my room and just could not stop thinking about it - and I tried to watch porn but that only got me to watch BBC porn and then I said what the hell ... I went downstairs and he was gone ... disappointed, i turned to head back upstairs and he pooped out of the bathroom and said, "I guess you changed your mind."

I had but could not really say much, he followed me to my room and by the time I had locked the door behind me, he had his cock out ... my first thought was that it was gorgeous and that I really wanted it but I made sure he knew that this was NOT who I was and this was my first time and I had no idea how to suck dick ... he told me to suck it the way I like my own cock sucked ... then it happened, I could not believe it but I was sucking his suck and loving it ... he moaned, held my head, told me what to do and I did it ... I could hear him getting ready to cum and I stopped ... he begged me to finish him off with my mouth, that he was clean and it would be so hot ... I just did not think I could but that if he wanted to - I would get on my knees and he could cum on my face and chest ... he stood up and I went back to sucking his very big black cock ... I was licking his balls when he called out that he was cumming ... and I will NEVER forget that first load of hot cum from a black cock ... I pulled away from him to watch this load and it was huge, cum everywhere - it was so sexy, so beautiful ...

This is where my questions come in ... why, after 40 years of never wanting m4m fun (or even m4t or t4m fun) did I love that hot load so much ... it turned me on so much that as he was still cumming, I started sucking him again and I tasted his cum (and i liked it) ... he was so happy, I just kept sucking his big black cock until there was nothing left ... even took the picture before of him soft to remember it by ... but after I took that picture, we talked and within minutes I was sucking him again, this time I just swallowed it all ... over that week, he visited me 4 times in all and came in my mouth 6 times total ... twice he made me wear his wife pantyhose (his idea) so he could grind his huge cock against my ass to cum ... I am married and I think i am straight but I have been home for 3 weeks now and all I can think about is finding a black man to suck ... any black men out there that want a white man that has just found the glories of sucking black dick - email me .. because I want a local black buddy to suck off (you must host)
