What is 3sum?

A threesome, commonly referred to as a 3sum, is a sexual encounter involving three people. Threesomes can involve any combination of genders and sexual orientations. They can be a spontaneous encounter or planned in advance with all parties consenting to participate. Communication, trust, and respect are important when engaging in a threesome to ensure all parties have a positive and enjoyable experience. Threesomes are a common fantasy for many people, but it is important to discuss boundaries, expectations, and safe sex practices before engaging in a threesome.
