So omegas can get over with their heat while being a top too?

Same doubt

as long as they can cum i guess

But in another manhwa named like a tidal wave-pheromone shower ig
The Omega tops generally but during his heat he craves for something to put inside so in general they want something inside right. But it's a fictional world so the author can do whatever he wants I guess ╮(￣▽￣)╭
