Being able to have a friend who can establish a three way relationship with you is not a rare thing. It is believed by many people that real friendship and sexual relationship cannot exist at the same time between two persons. However, that happened between my girlfriend and her best friend. We decided to have a threesome with her best friends after wavering between strangers on tinder threesomes dating apps and friends. It turned out that we made a smart decision. Since then, we have gone through 3 years of our three way relationship.
