Female led relationships discussion

My wife and mistress have asked if I can show more romance. They know this is a long shot for me since outside the home, I am the textbook brute male. I just don’t understand how or what being romantic looks like to me—is it buying her flowers and a card? Or running her a candlelit bath after a hard day?

Apparently, I’m lacking in this area, and I have to agree. So if anyone can offer some ideas, it would be greatly appreciated. I simply want to make her happy.
