thresome is it ok?

I know a few friends of mine who have them. Some of them love it and some only do it to make their partner happy. My opinion? NO WAY! I would feel so degrated if my partner and I had a threesome. If he wants one he can go to a brothel and do it. I guess everyone has their thoughts and opions and no opinion is right. At the end of the day do what you want to do. But if you have kids, my advice is to not even go there! It broke my heart finding my parents engaging in that sort of activity :(
