Neverwinter Forest it's about progress

It clicks, slowly. Once, when he'd been very young, he'd asked mom about Maman's sudden weight gain. He hadn't quite understood her answer then, at least not the parts about things called heat and sex. All he'd taken away from it was that Maman would be bringing new children, others to steal her attention. But now, he realizes he should have listened more closely.
Are you talking about sex? He blurts, staring at Mal even as the other looks away. And... heat? He tries to remember what his mother had said; something about sex being for pleasure, and sometimes for children, but only during a woman's heat. Combined with Mal's explanation, it's beginning to make a bit more sense.
I know what those are, It's only half-true, but he doesn't know that, or truly care. He's more concerned with the implications here; not children, which he knows he can't have because he's not truly a girl (he'll panic about the girl he'd met later), but the sex part. He's pretty sure they didn't do that, even if he doesn't know what the actual act looks like at all. But the touches had felt more intimate than his mother had made it seem, and now that he has most of the picture put together, he's starting to share Mal's reservations. So... you wouldn't want this, if that scent — the heat — wasn't on me? I wouldn't want it?
