Can you imagine telling your current partner how many people you've slept with before them? Or vice versa?
It's a fairly awkward conversation and one many couples choose not to have. After all, the past is the past, right?
Elite Daily took some couples to find out just how your significant others' 'number' affects us.
The results are pretty hilarious, while some couples seem to already be aware, others decide ignorance is bliss.
Would you want to know how many people your other half has slept with and would you have a problem telling them your 'number'?
