What’s the name of this manhwa?

Hello again. This is another manhwa I lost from my reads and I need help finding.

It’s an esper/guide BL; the esper is the top, and the guide is the bottom. Both the top and bottom are quite buff, and if memory serves correct, the top has white hair (I can’t remember the hair color of the bottom but it MIGHT be black). I think “S-class/S-rank” (possibly multiple S’s) is a part of the title, and they live in a world where people are ranked by their strength. The top is an S-class rank and his power is having strong semen(?) He beats the monsters that plague his world by blasting them with what is essentially “a semen beam”. The bottom is pretty low-ranking in power, but the top won’t leave him alone, so they’re forced to work together as the bottom is the only person the top will listen to. Not everyone in their world is strong, some are regular civilians, but one your powers “sprout”, you are basically forced to work for this big company that fights the monsters that come from these portals in waves (no matter what your ability is). AN extra thing I remember, the bottom somewhat has amnesia and can’t remember what his past life was like. The top is a horndog (shocker to none) who pounces on the bottom any chance he can get. (I apologize for how out of order all of this is, I’m trying my best to write EVERYTHING I can remember). Another thing I remember, on one of the days of their mission (to kill the portal monsters) they find a monster who is basically human (he’s the one who can turn into a lion), and despite the fact that he’s supposed to be evil, he helps them fight the other portal monsters, and he can’t remember anything (allegedly) from before he exited the portal, all he remembers is a voice telling him what to go through it.

I know this is a lot to read but PLEASE help because shockingly enough, I quite enjoyed reading this so please please help
