boy/girl guy/gal gentleman/lady man/woman male/female
When people mix pairs, it is most often to single out the woman. One of the most egregious is guy/girl. The use of "lady" is old-fashioned, and raises a red flag about what other "old-fashioned" ideas the speaker might hold.
The best layman's source I have found for health news is the Nutrition Action newsletter. They don't take advertising, they translate (fairly accurately) medical research into layman's terms, they give you a clue as to how to act on it and they DO follow up on subsequent studies that the mass media ignores. The subscription is also very affordable (~$25USD I believe).
Edit: I think one of the reasons that their health reporting is more accurate is that they use either subject matter experts or writers that at least have a science background rather than just an interest in science. It doesn't keep them from getting anything wrong, but it definitely cuts the errors down considerably.
I've already said why your position is unreasonable, but I'll say it one last time: These homogeneous populations with homogeneous behaviours don't exist. Even within cultures and within generations, behaviour differs according to lived experience. You will falsely rule people in as well as out if you rely on some kind of shortcut rule of thumb to indicate interest. This applies to both sexes.
Individuals can be consistent, populations are not. Men as a group do not all behave the same (aka "consistent" for their gender) or all have the same expectations, just as not all women behave/expect the same.
There has never been consistency at a population level when it comes to how men and women receive advances from the other.
If you start with the default assumption that women who are friendly are ... just being friendly then misunderstandings are far fewer. Most men who approach you are just being friendly rather than coming on to you. Do you require men to reassure you that they are not coming on to you as well? Most women are not into every man they interact with. It's not their job to convince you otherwise. It's your job not to assume.
Edit: There is also a reason why the sort of data that you are proposing to provide is usually accompanied by genetic counselling. You might want to consult a bioethicist about your proposal if you decide there is enough interest in the service.
