The sex is comfortable, you know what to expect and you know it's going to be good.

Since the break-up, your feelings have changed for your ex, but there's still probably a lot of love there – if he or she isn't a complete assh*le.

Your friends will shame you for letting them back in to your bed – but the next time they go to tell you off, throw them this little chunk of science.

These two studies claim to bust the myth that if you get freaky in the sheets with your ex, you'll delay your ability to move on.

In fact, they say having sex with your ex, even if you're in a horrible place about the split – isn't bad.

The first study, conducted by researchers at Wayne State University, Western University, and the University of Toronto Mississauga asked 113 newbie singles to fill out an online survey.

The newly dumped people were asked if they hooked up with their ex, how they felt emotionally and how attached they felt towards them at the end of the day.

The researchers then conducted a second study, but this time 372 people were questioned about sex with their exes and if they still held any emotional feelings for the ex.

And surprise, surprise – both studies concluded that contrary to popular belief, sex with an ex doesn't prolong heartache.

Additionally, the number of times you get freaky with your ex-lover doesn't play a role either. 

The results actually found it does the opposite – anyone who felt a strong emotional tie to their ex, sought out sex the most because they were trying to fill a void their ex had left.

BUT doing the dirty made them feel BETTER about the breakup – so honey, have your cake and eat it because this is emotionally risk-free.*

“This research suggests that societal handwringing regarding trying to have sex with an ex may not be warranted,” explained lead author Stephanie Spielmann. 

“The fact that sex with an ex is found to be most eagerly pursued by those having difficulty moving on, suggests that we should perhaps instead more critically evaluate people’s motivations behind pursuing sex with an ex,” she added.

So those late night booty calls are all golden baby – happy ridin'.

*This only works if both parties are single, and non-toxic. And don't forget to use protection.
