threesome complications- am i being unreasonable?

Well I agree with the above and all comments that are here. I know fantasy do come up but it best to talk about. I spouse if you are married and have threesome it all depends i think for a man most would love only woman but to be 100 faithful to your partner some but some fantasy should stay in fantasy world as some fantasy can break a marriage also like threesome. If you are single then I suppose a three some is ok but that just my thoughts on this.
