looking for male protag that finds a world he didn't know existed

[Travis]

I'm looking for any urban-fantasy books where the human is the male that finds a world he didn't know existed after meeting the girl. Book I'm aware of would be the "Beautiful Creatures" series as well as the "Underworld" series as well. I'm also open to LGBT+ books as well.

Thank you for your time.

The first I can think of is Neverwhere by Neil Gainman.

If I remember something else with all the specification I will let you know.

Oh. I thought you meant something more like The G Spot by Alice Ladas.

Too many men have never known that existed.
