Should I Do it or No 😩😉🤔

Bay • Hey y’all I’m 22 and living in CT
My ex's best friend is really hot and sweet and he wants to hang with me tonight but I know me being single and horny 24-7 I won't be able to kee my hands off him. And the guy I would be meeting has already asked my ex for permission to see me and do stuff with me. Is this a bad idea? I have no idea what do?
