Absolutely. Also important to note is that people interpret different types of actions as non-verbal love notes. My husband showers me with presents because when he gets a gift, he feels loved. On the other hand, since he's coming home in another week or so, over the last month I made some household repairs, had his car detailed, taught his dog a new trick, ordered him more checks, canceled a useless membership, dusted his collectibles, and got a very meaningful tattoo. I did that stuff because I feel loved when someone does things for me. When he's home, I touch him a lot, because I feel loved when I receive physical affection. To make absolutely sure he feels loved, I bought him a new wallet. He needs one, and I'm paying attention.
If you really want to capture someone's heart, watch how they treat the ones they love, and treat them accordingly. People treat their loved ones a certain way because to them, it means "I love you." This first dawned on me when I was feeling hurt and confused about a man I was dating. I really cared for him, and he said that was mutual, but he never kissed me, seemed uncomfortable during hugs, and wouldn't hold hands with me. On the other hand, if I needed something done, and couldn't do it for myself, he was (and actually often still is) the first to volunteer. Early in our romance, that guy hacked into my computer from his job in order to solve a problem for me. I think he's the reason I feel loved when people who love me do nice things for me (like bake for me even though I'm a pastry chef, or put away my laundry, or introduce me to their tattooist...)
My dude won my heart not by showering me with gifts (that's how he understands love, not I), but by cooking meals with me, preferring time with me over time with anyone else, being physically affectionate with me in ways he's not comfortable being with anyone else, comforting my friends when they needed- simply because it was important to me, fixing stuff at my grandmother's house, and yes, with great sex. Quality time, loving touch, and taking care of things for me get the green light every time.
