I’m a man named Bruno who loses interest in women after sex. Why does this happen?

The phenomenon of losing interest in a partner after sex could be linked to neurochemical changes that occur in the brain. Andrew Huberman explains that during sexual activity, dopamine levels peak, contributing to anticipation and excitement. However, after orgasm, dopamine levels drop and a hormone called prolactin increases. Prolactin is associated with feelings of lethargy and decreased sexual desire. This hormonal shift can influence the "refractory period" in males, after which they may not feel the urge to engage sexually again for a while 1.

Additionally, this hormonal interplay affects relationship dynamics. Dopamine facilitates the excitement and drive of forming relationships, while prolactin can create a calm, stable, but less intense connection post-intimacy 2. These shifts are natural biological reactions designed for recovery and can vary widely between individuals.

This biochemical explanation could help understand that changes in interest post-sex are partly influenced by natural hormonal cycles rather than purely psychological factors. Understanding these dynamics can be beneficial in managing and maintaining healthy relationships.
