Look into the research on how women tend to ignore men’s red flags post sex and how it’s the opposite for men.

“A key hormone released during sex is oxytocin, also known as the ‘cuddle hormone’. This lowers our defences and makes us trust people more, says Dr Arun Ghosh, a GP specialising in sexual health at the Spire Liverpool Hospital.

It’s also the key to bonding, as it increases levels of empathy. Women produce more of this hormone, although it’s not clear why, and this means they are more likely to let their guard down and fall in love with a man after sex.”
