Perhaps it can but that is not the best desired outcome. A man and a woman that are attracted to each other and love each other need more than just holding hands. That's just not realistic.
Of course it is. You love your family and friends and God without any physical attraction. In fact, we are not to love our family members in that way.
There 3 types of love. God loves us in the Agape way, which motivated by actions and not feelings. Philos is family/friend love. And Eros is romantic love between a man and a woman. That has usually been described as being the lowest of the 3.
And for good reason. One reason there's so much divorce is because we want to be in a constant state of romantic attraction, which is not possible. Besides, for centuries marriage was a matter of economics rather than being in love.
That's why arranged marriages tend to last longer, 'cause it's not about romance but a conscious decision to do what's best for yourself, your spouse, and your community. Marriage affects all of us.
