I remember hearing a saying that goes like "men think of sex every 7 minutes (or seconds?)". I take this saying to mean that men have sex related thoughts more often than women.
I'm interested if these thoughts are related to hormone expression within the male body. particularly, I'm interested in the very few seconds before a sexual thought emerges - one moment a man is thinking about daily stuff, next moment his thinking has sexual content. What is responsible for this shift in thinking?
I've read that oxytocin is responsible for men feeling romantic attachment to a partner, but is there a hormone that initiates sexual thoughts or fantasy? For example, would a burst of testosterone increase the likelihood of a man thinking of sex?
