Does he tell you he loves you when you least expect it? Does he flutter your heart when he kisses your neck? No scientist or biology, it's obvious when he's holding me It's only natural that I'm so affected And my heart won't beat again if I can't feel him in my veins No need to question, I already know It's in his DNA, d-d-d-d-dNA It's in his DNA, and he can just take my breath away Breath, breath, breath, breath away I feel it every day, and that's what makes a man Not hard to understand Perfect in every way, I see it in his face Nothing more to say, it's in his d-d-d-d-dNA It's the blue in his eyes that helps me see the future Fingerprints that leave me covered for days, yeah Now I don't have any first degree, but I know what he does to me No need to work it out, it's so familiar, oh And my heart won't beat again if I can't feel him in my veins No need to question, I already know It's in his DNA, d-d-d-d-dNA It's in his DNA, and he can just take my breath away Breath, breath, breath, breath away I feel it every day, and that's what makes a man Not hard to understand Perfect in every way, I see it in his face Nothing more to say, it's in his d-d-d-d-dNA His smell about his kiss, contaminates my lips Our energy connects, it's simple genetics I'm the X to his Y, it's the color of his eyes He can do no wrong, no, he don't need to try Made from the best, he passes all the tests Got my heart beating fast, it's cardiac arrest He's on a different strain, the science can't explain I guess it's how it's made in his d-d-d-dNA Oh, oh, oh, oh, oh It's in his DNA, d-d-d-d-dNA It's in his DNA, and he can just take my breath away Breath, breath, breath, breath away I feel it every day, and that's what makes a man Not hard to understand Perfect in every way, I see it in his face Nothing more to say, it's in his d-d-d-d-dNA
