Do thresomes ruin relationships?

I have not tasted threesomes sofar but i think it can be really enjoying if all the three partcipants agree wholeheartedly for this adventure.we should have all the fun in life as life is too short and we all will go away from this world very soon.

Im not to sure about that i think the relationship would have to be strong and there will have to be lots of love there cause i think jeliousy would get the best of me i cant share..

i guess theres no actual relationship goin on if u look forward to threesome...so where does the idea about relationship getting ruined come?

No they make things better and more fun!

Hmm, this is an interesting question. My bf and I havd talked about it, just sharing our opinions, and we agreed that if it ever came to that, then we would be doing everything and the third person would sit and watch. Because I don't want him doing anything with anyone else, and I don't want to do anything with anyone but him. I guess it can be fun for a more adventurous couple, but I can only assume that it would make cheating easier and the relationship weaker. Though I don't know, maybe it builds a stronger bond in some strange way.

It really depends. If your partner is not open to this type of relationship. it would surely ruin your relationship
