According to research published in Communication Monographs, part of the 'orgasm aftermath' is an overwhelming urge to tell the truth and share information with your partner.
The reason being, Oxytocin (the social hormone apparently) floods a person's brain during orgasm. This leads to increased levels of trust, meaning people feel safe enough to let their guard down.
"Post-coital communication is likely linked to sexual and relationship satisfaction," explained Amanda Denes, Assistant Professor at the University of Connecticut, lead author of the study.
"For this reason, pillow talk may play a pivotal role in maintaining intimacy."
However, wine drinkers take note, pounding a bottle of vino blanco before sex has the opposite effect and people are less likely to share after sex.
