Well if it's advise you want getting your game out there I would recommend a good marketing firm...
But seriously, your game is still in early stages so the battle uphill will be difficult and your commitment to the cause will be shown as the game develops, IF it develops.
Call me old fashioned but for me personally, as a matter of principle, I treat my projects as hobbies first and see what comes off it, rather than a basket to fill money in. Unfortunately, or fortunately depending on how you look at it, we're living in times where these types of porn games took off like a rocket ship, and competition is rigorous.
I would focus on good plot first, and good gaming mechanics second, as well as interface. Then renders of good looking characters, environment and texture and finally animation. If you don't have anyone else helping you out, you'll have to market yourself on social media. Some of the most successful games even go as far as making trailers of their games but that's only if you really expect great things.
Lastly, it's a good idea to start with regular updates, and keep true to them, specially at the beginning stages. I can't tell you how many times people complain about a game dev never meeting the quota they themselves set up. Plus, it boost up your game in sites like these ones and makes it more popular as a consequence.
Anyway those are my two cents on the matter, believe or not I'm on the side of the fence where I rather see more people make games like these, it's a great contrast to the censorship in mainstream gaming we got going on these days.
