wanna have a 3sum?

Open relationship 3 some. Now when i was in Florida i saw a "open relationship 3sum" and it happen to be 1 guy and 2 girls. Now i could be wrong the girls could've just been drunk and was like fuck it. Or i can be right. I'm saying they looked ditsy (is that word) but anyway im thinking could i ever see myself in a "3 sum relationship" now they got there bad side and good side.
Good side:
- If im not feeling you today you go to that other bitch.
- 1+1+1 = New tricks in bed
- Fuck cheating i can have both of y'all
Bad Side:
- Jealousy much?
- How im going to explain this to my mom?
- All us walking outside holding hands. Crazy
To me being in a 3sum its more of a mental thing. If you can say okay i find myself happy with these two people. Then go for it. Some people frown on it. Others are close door about it. Akon confess he practice polygamy and he have 3 wives. He sees he can afford to have any wives as he please and this is normal in Africa where he's from. And that he treat all his wivesequal. But im guessing his management don't want him to promote his polygamy. Because stuff like this is not "popular" But in africa this is perfectly normal and your only allowed to have 13 wives.
