Help with Hypersexuality/sex addiction

This is my first time actually asking for help but i think i really need it. Its going to break up my marriage and i do not want it to..

I love my wife and kids and wouldn't do anything that might push me away from them. Even with BP2 i have been able to stay away from trouble but sex is the one thing that i cannot resist. Its ridiculous because its not like i want to sleep with them because they're hotter than my wife because they're not. But I still manage to do it and as soon as its done i just have guilt for days. I tell myself its the last time but it never is, as soon as i get a call or text i never say no. I want to stop doing it. Has anyone had this problem? if so any advice on how to keep it at bay?.

currently taking lamictal
