Do you believe you can "teach" a man to be romantic or does it have to come naturally?

Can you teach romance to a man or your s/o?
What makes one man romantic and another one
not so much? I have a friend that treats her husband
like dirt but he is so romantic to her it would make me
melt! If your husband isn’t romantic does that mean
he doesn’t love you as much as a husband that is
super romantic to his wife? I guess romance is different
for each couple. What do you think?
