It doesn't sound super shocking when you hear it but the results of a study are shocking! If your girlfriend fakes an orgasm she is more likely to cheat on you.
The study took 138 females and 121 males and asked them about the frequency and quality of their orgasms as well as how many times guys actually thought their girl climaxed.
What they found? A history of infidelity was definitely connected to the amount of fake orgasms. The study also found that it didn't matter number of orgasms just REAL ones. So even if you didn't have a lot of them, you're better off than faking them!
Good luck, gentlemen.
