[General] How do mermaids have sex?

Mermaids and mermen don't have human genitals. So, do they not have sex? Do they just lay eggs or something? In that case, why would they ever fall in love when there is no purpose to that evolutionarily speaking?

They don’t have *visible* genitals. Given that mermaids have breasts, it’s reasonable to assume they’re mammalian. That means they breed in the same way whales and dolphins do. Hidden dicks into hidden vaginas.

Hell, that’s not only how sea mammals do it. Sharks also have hidden dicks.
