So, one of the races in my headcanon is a race of draconic humanoids (dragonkin/dragonborn, basically). One of their salient features is that the species develops the ability to spit a pyrophoric, oily "venom" from a young age and retains it throughout life -- this effectively is a short-range breath weapon of sorts, capable of inflicting painful if not crippling wounds or even killing its victims outright if the wounds are not promptly tended to. It evolved from the ability to spit ordinary venom as a defensive weapon against predators that kept evolving immunities to various poisons. As a result, both genders have it in equal potency, but it takes a long time for the venom glands to refill after they're emptied of their dangerous contents.
Otherwise, they're fairly typical for dragonkin, bestowed with tall (1.8-2+m), heavy builds as well as scales over their leathery skin. While their scales and skin are resistant to ordinary burns, their own breath weapons still pose a serious threat despite this. Reproductive-physiology-wise, they are oviparous, internally fertilized, and operate on the one-hole plan (i.e. they have cloacas), if that matters at all.
So, what differences in mating and courtship rituals would there be between my dragonkin and regular humans, considering the stronger consequences that a violent failure of courtship poses to both parties involved? (If you wish to be specific to societal time periods -- you can use a late medieval/early Renaissance era human society as a reference point.)
