Prelude
This is just a heads up on what to expect going into the story as it isn't for everyone.
First look at the tags! The story is normally light hearted but some of the villains in the marvel/DC universe aren't great people. The first arc involves the protagonist fighting mind controllers. Just google the purple man and you'll see how bad they can get and the new villains added are arguably worse than him. Bad guys are really, really bad in this story. One of the women who he sleeps with is in a relationship but already cheating on her boyfriend.
The story will have magic in it and one of the choices makes him one of the most knowledgeable people in the universe when it comes to magic/chi. The magic system is completely made up by me and it's a simplified cultivation and magic circle system that I have to brute force to fit into the world. If the explanations don't make perfect sense or a hundred chapters later I decide to add something new to it that's why.
The sex scenes are pretty basic at the start but becomes about satisfying his partners kinks. Every women he comes across isn't going to be throwing themselves at the him and most of the first girlfriends he gets are doing it for the benefits he can provide to them. A good portion of the ones he sleeps with wouldn't be his first picks if he was building the perfect harem for himself.
