Bisexual with doubts

I need help from the community because I can't take it anymore. I'm coming to tell you that I need cock! I'm a married man in my late thirties with a beautiful wife of the same age, but since my adolescence I've always had the curiosity to pick up the little thing, if you understand me 😉 I always fantasized and played with my Booty, but never got around to anything because of prejudices. The years passed and life gave me a partner who was just as or more morbid than me. She, with much experience, slowly took away the card of what I liked and started pushing me to try new things. She knew how to contain me and find pleasure in my tastes, and by god, it's lovely that someone understands you and takes care of your tastes! We started with black kisses, a finger, contradictory questions, toys, and we're going for the belt and white kisses (I LOVE white kisses). But despite all this, she doesn't have something that I really want, which is the need for a man to make me his slut and feel good fucking and full of cum like god intended. We fantasize about threesomes and, although I still can't believe it, the idea of a bisexual threesome where I'm passive heats her up. Sorry, I'm making this long but I love being able to get this out of my system. What I want to know is how to keep going. Where do I find the chongo? In friends? Ex-boyfriends? A complete stranger? Is it worth it? Or am I condemning the partner? I know some of you will understand me and can give me a hand with your experiences. On my part, I'm still the slut of my wife sometimes, and I love it!
