Nah your english was fine, he was just teasing you.
But how it's going to work mechanically is a good question. My guess is, we CAN be compatible with all the girls, but we aren't automatically given we're a human and they're all various species of fury (and I'm sure scalie later as they were mentioned. And th bird people too). So to be able to actually get them pregnant will involve us going on quests and getting stuff. But it'll be per girl/species. So what will get the mouse girl pregnant won't work on the fox girl etc. This will allow for expanding the story and the world while allowing for sex to be hand and the introduction of more characters. But then again, a lot of games that will have pregnancy wait an unlikely amount of in universe time before the girls ever actually get pregnant with no in universe reasons for it despite all the unprotected sex.
