The only race I’ve really thought about this is with the three-gendered version of my Orcs.

My orcs are divided into:

• ⁠males — huge, hulking brutes that are born roughly 13% of the time.
• ⁠herms — which, while all equivalent in reproductive organs, can be male-presenting or female presenting (depending on how much of each parent’s pheromones they grew up around) and make up about 36% of births
• ⁠females — the remaining births, who grow to become small, slim, speedy, and extremely flexible.

Since all three need to be involved to produce a child and since herms experience physical changes while their male partner’s seed is keeping them fertile (skin tone changes in response to hormones), the risk of actually producing a child is extremely low, and almost zero if only two genders are involved (though there is a singular exception to that).

This means that, with less risk of a child, sex tends to be way less taboo, with outright public sex being crass but not criminal. Gay/lesbian sex is even less frowned upon, as the culture of Orcs tends to separate males and females due to their size differences, thereby raising kids in a mono-gendered environment, which subtlety encourages homosexual experimentation.

And because of the nearly zero chance of children being sired from a two-person relationship, familial relationships are very common, often to the point that most orcs lose their virginity to their parent.

There’s no minimum age of consent for orcs. However, their psychology instinctively demands that their mates meet certain characteristics, such as the size or shape of certain body parts, and those combinations simply don’t exist in prepubescent orcs (tusks grow in at 12-15 years old, and the ears don’t start lengthening seriously until 13, for example). What we would consider pedophilia is something like a thousand times rarer among Orcs due to this, but they also don’t find it as despicable when it does happen.

So, while a kid isn’t likely to have sex until they’re a teen, their parents often have no complaints about them being in the room at the same time — and if they’re old enough, the kid might just be invited to join in. And if not, well, it’s no big deal. It’s basically a non-issue to them.

That said, they do recognize that other cultures exist, and that not everyone is as sexually open as they are.
