If you're
finding a threesome partner, try 3rder, an app for couples and singles to "
threesome." It works exactly like Tinder -- that is, you can search by distance, age and gender, and only match when both are swiping on the other. The only difference is that you and your woman have the same profile and you are looking for a third person together. Pro tip: meet your potential guest star IRL before committing.
