Sorry, but I strongly disagree. Men may know right away whether they feel a woman is sexually attractive, but in my experience, no man can really instantly know if a particular woman is one he’d consider for a long-term relationship.
What’s my qualification for saying so? 27 years of a very happy marriage, of true love (yes, there is such a thing) to my lover and very bestest friend. I knew her only as a friend for a full year beforehand without even a thought of a long-term relationship…because at the time I was married to (and loved) her friend. That marriage ended before I even thought of the one with whom I am spending the rest of my life.
So I’m sorry, sir, but you’re wrong. My life experience proves otherwise.
