Ok, I'm gonna cut through the 5 pages of answers by asking you 2 things that get to the root of your question:
Have you defined 'love'? And where have you got your definition from?
For example, many 'love' stories, especially in films, show only the courtship period between two people. Undoubtedly this is fiery and passionate, but when this definition of love is used, it can mislead girls especially into thinking a long term relationship can maintain this intensity. Then, when the 'love' story is made tragic, where one of the lovers dies, it can lead to further misguided fantasy. Tragic love adds the emotion of grief, which is perhaps the strongest emotion of all, but it's something we feel primarily from our separation from our mother. In other words, if you dwell in the grief of a tragic love story, it suggests it's not so much about a romantic man but your own feelings of mother's abandonment from childhood!
What about friendship? Friends are those who care about each other's wellbeing AND in keeping up to date with each other's narrative (ongoing story). Plenty of guys can do this with each other. Doesn't mean they 'love' each other in the sense of being a romantic couple. But sure there's a care there. I like to distinguish between friends and playmates. The latter means there's a fun chemistry but without the care.
What about sex? Yes, guys do enjoy sex and lots of it. In my opinion, guys need to sexually explore with various women before they are willing to commit to an exclusive, long-term relationship. But here's the big secret. Women love sex too. They are sexually repressed by society's narrative though. It's only when they are in the socially acceptable conditions of monogamy and commitment that they can really let go and enjoy the act in itself. Every female I know, friends, ex-girlfriends and even strangers have told me how much they enjoy it.
So what is 'love' between two people in a long-term relationship? Using a breakthrough theory in neuroscience that outlines our basic emotions, I'd say love is a mixture of the following: GRIEF release when you feel lonely, CARE for a partner's wellbeing and narrative, PLAYfulness provides a light and easy-going tone for a relationship destined for 50plus years, SEEKing out projects together provides longterm substance for your joint narrative, and of course, LUST for each other until it fades.
Hope that gives you a bit more information!
