Married curious guy scared of the slippery slope after achieving my fantasy

I've been fantasizing a lot lately about sucking uncut cock and even started to chat with guys and search locally for someone to suck. I've seen a lot about how once you have your first gay experience it can be a slippery slope into becoming a full blown cock addict. Part of me hopes I will hate the experience and it is better left a fantasy, but the other part of me hopes to unlock a whole new world of sexual freedom with men and women. What's better/worse is thinking about becoming submissive and slutty to the extent where I'm the center of a blowbang with uncut dicks. Anyone else have this anxiety?
