I Have A Sex Addiction?

For reference, I'm engaged and getting married in a couple months. I'm recovering from a gambling addiction. Since stopping gambling and also because of the countdown to the wedding I'm craving this adrenaline and more and more attention. I've gone through a lot of emotions and a few crying breakdowns in the past couple months. I've been feeling guilty and also horny as I've ever been. I feel like I'm sort of having a new addiction. I've had a few instances where someone would look me up and down and I'd instantly get turned on. In my GA meetings, there's this really hot guy that I always see. The past couple times, I'd be sitting there and my heart would start racing, feeling like I can't breathe, an overwhelming sensation of heat between my legs as I run scenarios through my mind with that sexy man. Yesterday at breakfast with my fiancé, I wasn't even triggered, no hot guy, but that sensation and urge came over me again. He thought I was just hungry. Nope. The heat was rising, my leg was shaking and my heart was racing. My fiancé knows this has been happening. But I'm so nervous I might end up acting on it one day. I'm scared the old me might come back.
