There's a science for everything! And now the science is saying how long you should spend with someone new when dating... BEFORE you spend the night together!
It's an age old question as to how long you need to wait. What's right and what isn't? Well, the psychotherapists have come up with the number!
Here's how long you need to wait...
36 HOURS!
They don't have to be consecutive... just enough dates to add up to 36 hours. If you wait any longer than this number, the desire can begin to fade.
