Why do men often wake up with an erection?

Do you really know? ·

2025/11/25

A lot of people think that morning erections are triggered by erotic dreams, or a need to pee, but in fact they're a physiological reflex linked to sleep. That’s right - they’re not dependent on sexual arousal at all. And in a somewhat similar way, women actually also experience increased blood flow to the clitoris during the night. Now, the scientific term for a nighttime erection is nocturnal penile tumescence, or NPT for short, and men get a few each night on average. They occur during REM

Do you really know? ·

2025/11/25

It is a bit of a stereotype that the Brits love to moan, with the weather and Brexit being among the most common causes of grumbling around the country.
