HELP!! Combinations have me so confused

So I found a website last year that did all this for me when I was trying to do it, but I cannot for the life of me remember what I googled to find this so I am starting from scratch because every thing I am coming across is not helping. 

I have a list of 22 people (11 guys and 11 girls). I need to find all the possible combinations of making 11 couples out of these 22 people. 

Andrew    Asia

Brett         Bria

Cam         Cali

Dan          Jasmine

Kwasi       Kayla

Lewis        Kenya

Moe         Lauren

Shamoy   Maria

Tevin        Morgan

Tomas      Nutsa

Zak           Samantha

so I was able to use a formula to determine how many possible couples there are (which is 247) BUT what I really need is to find all the possible ways to arrange these couples into 11 possibilities using each of the 22 people if that makes sense. 

If you have ever seen the show Are You The One, this is for that show. They take 11 guys and 11 girls and stick them in a house and it is up to those 22 people to figure out which is the correct combination of couples to where everyone is paired with their perfect match. 

But this is giving me a headache trying to remember how I found all the possible combinations of 11 couples last year!! PLEASE HELP!
