I'm glad to hear that you finally had the opportunity to suck another man's cock and realize how enjoyable it is to do so. Pretty close to how I felt after sucking my first dick so many years ago too.
I've only done it when I've been out of a relationship with a woman, which always gave me the guilt-free freedom to enjoy cock, so much. In fact, the first time was after my girlfriend of 3 years broke up with me at 30 and broke my heart. Gay desires for the first time flooded my mind, and drove me mad with lust. So I finally visited a gloryhole booth in a video arcade. It was the most surreal, scary and exciting-at-the-same-time experience I've ever had. When that first real cock came through that hole and was right there in front of my face, I had hunger like I've never experienced. Feeling that both hard and soft cock at the same time in my mouth was unbelievable. There I was, me (!), sucking another man's cock, and loving it. I didn't take his cum into my mouth that first time, just releasing my lip lock and stroking him to have his cum shoot across the booth 2 inches from my face, but I watched in absolute reverence of that beautiful cock shooting cum, that *I* caused to happen. That feeling just can't be described in words. And was I ever hooked! I went on to suck so many cocks and enjoy the taste of so much cum before swallowing, and even fuck guys, actually inserting and penetrating their assholes and fucking them. That first time fucking another man, at 51, was the greatest sexual experience of my life, which I've written about a lot in this forum. At 63 now and having broken up with my last girlfriend from a long-term relationship, I'm happily continuing my adventure with guys. Deep in my heart I know that I was born to suck and fuck other guys.
The only drawback to making the leap is that cock lust becomes a thing. Anything longer than two weeks between blowjobs and I start to lose my mind. No amount of jerking off fixes it, either.
