partners they could hypothetically reproduce with

"fertile women"

"women capable of pregnancy"

Outdated, slight red flag option: "gynephile"

Or you could even try "I find women attractive and would love to have kids with the woman I love one day"

There, language isn't that hard.

You thought you ate with this comment 😂

Do you often find yourself in discussions where the trans-inclusivity/exclusivity of the term is important to know?

Because whenever I use "men, guys" or any other such term, whether it includes trans people doesn't even cross my mind. Like the discussions if we should welcome "guy friends" at our girls' game and gossip nights, or if I'm being too naive around "men". Talking about "males" like an alien species would be weird and mildly offensive. (Mildly because the Finnish word "uros" can imply admiration for a man's masculinity.)

If you wanted a term for potential partners you could possibly reproduce with, none of the "female, woman, male, man" terms by itself would do, because (even personally known) infertility for various reasons exists.

Just say what you mean. Intersex and trans people exist. For example, "menstruator" or "people who menstruate" if you're talking about periods. Not all women menstruate, not everyone who menstruates is a woman, and hell, there are plenty of people who have uteruses but don't menstruate. It's way clearer and inclusive.
