Having threesome with best friends, yes or no?


Today, I would like to talk about the subject of having threesome with best friends. I know many people have had threesomes with their friends and many people prefer to have it with strangers they met on tinder for threesome apps. For me, I am going through this choice right now. My best friend suggested to have a threesome with us. My husband, of course, he is okay with it, but I am not so sure. I am afraid that it could damage my marriage as well as our friendship. What do you suggest?
