Sex addiction and cheating

I'm in a relationship and I've been dating the guy for almost 2 months now (woo 🎉).
Great guy and all, nothing to complain about... However, I'm a sex addict and crave the need for another person in such a close, intimate manner. I feel so so terrible because I've cheated on him with 4 guys, slept with them all, and reguarly see them. I haven't told him and I know I should because it's the right thing to do, but he's so good for me. Not in a relationship type of way, well yeah thag, but for my mental health I mean. He's helped me through a lot and I absolutely adore him... I just don't want to hurt him. I crave the need for a relationship, to have some sort of stability in my life, but then again I want to go out there and just simply have fun with guys. I want this guy so so bad, but then I want something that ruins that type of want from me and it's killing me.
It's hard for me to stay with one guy. You can shame me however you want, it doesn't phase me. Just feeling lost hey...
I don't know what to do
I'm going crazy 😪
