I very frequently find someone attractive, or not, long before seeing their genitals. Indeed, there are dozens of people in the world whose genitals I have never seen, and yet I am still able to find them either attractive or not.
Compatibility of genitalia is surely important for answering the more specific question “am I going to have sex with this person or not?” but that’s not the same thing as attraction. For most of us, there are plenty of people in the world who are very attractive but with whom we will never have sex. Many people choose to have sex with people they find not all that attractive (e.g. because they are in some sort of long-term relationship, and either their tastes or the appearance of the other person have changed over time).
