First, you need to figure out why you want to have a threesome, especially for couples. One of the potential dangers of threesome is that it can possibly damage your current relationship. Threesome requires to invite another person to share bed with. In other word, you are about to share your husband or your wife with another person. Why do you want to do that? Is it because you want to have sex with another person? If yes, this is not the right reason to do it. I suggest you to give up that thought if you still want this relationship with your partner. If you are just wanting to explore some more bedroom fun with your partner, then yes. You can go ahead and enjoy it if your partner is on board with you.
Second, if you figured out the reason why you want to have a threesome and you still want it, how to tell you partner about it without letting him/her misunderstand your motivate? "I want to have a threesome with another woman". Is this the right way to ask for it? Absolutely no. If you ask for it in that way, there is chance that you may get dumped for it. She/she would think that you want to have sex with another person. "Honey, I think it would be a huge turn on seeing you with another woman". How about this? Better? This is the right way to ask for it. Do not include only you when you ask. You can say only your partner or you together.
Third, how to find a threesome partner? No matter you are a single or a couple, threesome dating apps or sites can help you with this issue. Threesome dating apps and sites can be very efficient and simple to find a perfect threesome partner for you. But please remember that safety comes first. You need to make sure she/he/they are safe.
Forth, how to have my first threesome after everything is ready. Communication can solve it all. As long as you have questions or doubts, just ask. If there is something you like or don't like, speak. There is nothing to be ashamed of and there is nothing should be hidden. You should be 100 percent honest with each other, or you won’t be happy and satisfied during the process.
Wish you a wonderful first threesome experience.
