Just start drawing every day, start by copying some artist with a style you want to imitate in order to learn, and don't worry about being original. Nothing is original anymore, just copy something you'd like to see more of and market it to people. There are plenty of websites that serve as platforms for ecchi artists and you'd be surprised how fast you can grow a client base if you're decent.

Honestly, porn is good money. If you don't mind it, go for it.
