- Description from novelupdates

Just before being summoned to another world, the protagonist’s summoning medium was secretly swapped by someone. As a result, he was not summoned as the “Holy King” but instead as the “Sex King.”The magic he can use includes water magic in the form of lotion, fire magic as candle wax, and his summoned beasts include a wooden horse used for punishment…Branded as “vulgar,” “useless,” and “filthy,” he is rejected, has his engagement annulled, and is ultimately exiled. However, the one who picks him up is a princess from a nation where the sex industry is legal.Using his modern knowledge, the protagonist begins rebuilding the nearly bankrupt sex kingdom. He introduces new fashion trends unknown to this medieval world and uses his authority as the Sex King to subjugate the girls. He then establishes modern sex service techniques.The protagonist's method of leveling up is through intimacy with his heroines (his concubine maids). The more intimate he gets, the stronger he becomes, and the wealthier the kingdom grows.However, the surrounding great powers will not stand idly by and allow a flourishing nation full of women. Thus, the flames of war are ignited.Utilizing his creativity, adaptability, and cunning, the protagonist repurposes his sex-related magic for military applications and overwhelms his enemies.As he gradually awakens to the path of conquest, he begins walking the road of a ruthless emperor. However, by his side is always a heroine, a celestial beauty who keeps his heart from straying too far…

He was a loser in his past life, useless, but at least he never truly lacked anything. He had money, food, a roof over his head, and everything he thought he needed.He had never fought a day in his life, he didn't need to struggle for his life.Then he got hit by a bus… and woke up in another world.A world where destruction and bloodshed were the norm. A world shattered by apocalypse, where people lived on floating islands and sailed across the skies in airborne ships. A world where the weak had no place to survive.Now, he inhabits the body of a Dragon, the weakest of the royal bloodline. A cursed runt abandoned by his siblings, carrying their curse.He is now known as Kaedros, the Dragon of the Sun.He was banished and thrown into the human territory, to fend for himself in the midst of the enemies that wanted him dead.But now as a Dragon, given a second chance, he didn't want to waste it by being a loser a second time. This time, there's inheritance to claim, territories to conquer and galactic, dimensional enemies to fight._________________So I'm going to add this. The pacing is going to be in the middle, not fast or slow. And the MC won't just get insanely overpowered at the start.He's not going to be a weakling either, after all from the title, you already know how things are going to end.I value character developments, so you'll see a lot of that as well.Things are going to develop in a reasonable way.Ps— you're already adding this to your library, so just start reading now!!

After experiencing heartbreak from being abandoned, he enlisted in the military.

And then, he became a war hero.
