Should I walk away or confess

Would you have sex with someone you have feelings for? Okay so here’s my situation. My friend and I have known each other for over 5/6 years now. Everyone once in a while we hook up when we not seeing other people. There are times I distance myself from him because on the down low I have major feelings for him. My now ex-bf and I broke up about a month ago. So I have feeling horny and started talking dirty to my friend. Long story short we hooked up last night (amazing mind blowing sex lol). Do you guys think I should put my feelings on the table or cut him off for good?
