Hi! I have several plots open for writing with a male (or a female who is okay with playing male characters). I have a couple of different available genres, but you should know that all of them are going to include romance to at least some degree
Best friends since childhood, it seemed natural that the pair of them would start dating when they reached high school. He was her first kiss, and she was his. They seemed destined to be together. But the world outside their hometown called to him and, after high school, he left for university, and left her behind, heartbroken.
Years later, he has graduated university and gone through at least a half dozen girlfriends since her - the relationships always ended because they could never compare to her. The death of a distant relation has called him home, and he sees her for the first time since he left. He finds that he wants her back, but she's not sure she wants him after the heartbreak she endured. Determined to win her back, he decides that, this time, he isn't leaving again without her.
(Potential supernatural bent: either he has become a supernatural of some type while gone - potentially a vampire - or she stayed behind because she is a part of a secret cabal of witches who demand that she remain at home)
Monsters exist in the darkness of our world, hidden in the shadows and preying in humanity. A young woman begins to get precognitive dreams about attacks and, unsure of what else to do, attempts to stop them. She comes to the conclusion that she alone is aware of these monsters and attacks, and is the sole protector of humanity. She is not. There are supernatural beings that exist (that she is not aware of) that also act to protect humanity - he is one of them, and comes to her rescue when she gets in over her head fighting one of the monsters.
The exact type of supernatural that you play is up to you, as long as it makes sense for the urban fantasy nature of the game
During the Old Republic era, a young Jedi rebels against one of the main Jedi tenants - emotion leads to darkness - and gets expelled from the Jedi academy as a result. Determined to help the Republic in the war in some other capacity, she signs on with a roguish starship captain under the guise of a mercenary.
This plot would primarily follow the relationship between the Jedi and the captain. I envision the plot involving 'missions' of a type, but they would be more episodic. If you have a good idea for an action-y sort of plot to tie into that, I would be happy to incorporate it!
The Leviathan - a massive airship thought lost after an accident many years ago - has reappeared in the Seven Skies. Around the same time, a captain without a ship receives a note inviting him to a clandestine meeting in the free city of Archon: the city of pirates. There, he meets with a young woman, a savant engineer, who weaves for him a story about an airship that requires almost no crew and promises him wealth and power in exchange for his aid... for the new Leviathan needs a real captain, and a crew of hardened men who will follow him. "I have a ship without a crew," she says, "and you a crew without a ship."
In this RP, we would play as pirates on the mechanized airship The Leviathan. Basically, the concept is that the ship flies itself with minimal control from other people. I would play the engineer, who found the ship's wreck and rebuilt it as the current wonder that it has become. She seeks out the pirate captain - played by my partner - because a ship like that still needs a small crew for boarding actions and other such attacks.
