If your partner and you are both the same height, isn’t that a cool thing? You would look into each other’s eyes without one lowering and the other raising their vision. You would smooch without stooping or raising yourself, as the case may be. Of course, you would still need to tilt your head. Perhaps best of all, you could theoretically make out standing too, without one bending or the other stretching.
The benefits go on. She wouldn’t buy heels, for neither may want her to look taller than you. If a queer couple, and with their famed fanaticism with fitness, you could possibly wear the same clothes, or each others’, and the latter also becomes a romantic / sensual / erotic thing to do.
