I don't gender the Court cards. (Or any cards, really.) Most women in my life appear as Knights, and I have a male friend who consistently shows up as The Empress.
Regarding your question, the Queen of Cups traditionally symbolizes a reflective, deeply resonant "understanding" of the other person. It's raw emotion without rational contemplation. The vibrations are purely sensory, relying on hunches and abstract, sentimental connections. So this male in question probably feels a strong connection toward this woman without logically understanding why -- he just does. It might even be based upon subconscious "cues" he picked up from her. For example, her body language, her tone of voice, or some offhand comments she made that he attributed significance to.
This Queen has a knack for intuitively picking up signals and absorbing them, even if they appear unruffled on the surface. But unlike the High Priestess, the Queen of Cups will readily expose their emotions when the circumstances feel right. However, they can also have a propensity to be extremely timid or indirect, which I've also experienced with the Cuppy Kings.
It's helpful to think of Courts not just in terms of biological sex, but in terms of the "energy" this particular person embodies. Even if it's merely situational.
