Hey, did you know you can use the search function next to the Free Gift button to search the forum for threads before you post? Threesomes happen to be a really hot topic and there are about 298 threads on the forum.

And to answer your question, yes I do believe threesomes can hurt relationships if people choose not to abide by the rules and boundaries they set. You have to be one-hundred percent honest in communicating your thoughts and feelings. Even the most seasoned swingers and couples in open relationships still have bouts of jealousy and insecurity at times. If it's not handled carefully and properly, there's a potential for disaster.
