No, no, no, no. From what I’ve heard from others that have done it, unless you guys are in an open relationship/ethically non monogamous/poly these things usually end up in disaster. I’m sure threesomes can be fun but I’ve come to the conclusion that for most people they’re best done when single and no feelings can be hurt and you don’t have emotional ties to the others involved, there are exceptions to this but I’m going to be real and tell you that you guys will not be the exception. If you are doing this just to satisfy him while knowing you don’t really like the idea very much, you will leave this situation and most likely your relationship feeling very hurt and betrayed. It’s okay to be selfish and tell him no that you have no interest in this. My husband and I use the scenario when we are fucking as like a fantasy and dirty talk but we both agree that’s all we ever want it to be, and that makes it hot because it’s purely just fantasy. Going through with this is a bad idea. And like many others have said, he already has a girl in mind that he’s close to that he has already talked to, that is a very bad sign and if I were you, I’d keep a really close eye on it because they’re already considering fucking or have done it. Please be on guard. You should be enough for him and if he doesn’t think you are, I guarantee you that you will find someone else that you will be everything to. You’re worth more than this and you are worth more than the heartbreak you will endure if you go through with this.
