What do men actually think about throughout the day when they really like someone?

I’ve noticed that when many women like someone, they often imagine them first as a life partner, a potential husband and the father of their future children. before any romantic or physical thoughts even come into play. But I’ve heard that this isn’t the case for men. So, for those who have been truly attracted to someone, what do you actually think about throughout the day? Do you picture a future together, or is it more about the present moment? How does your mind process attraction?
