Art quality aside going down this road is not really healthy. sacrificing creativity in substitute for self insert romance slop and sexuality. I know from experience that art takes a lot of time to make and perfect, wasting your talents and spending 1 - 2+ hours on really shite looking pornography is a waste of time. The guy's brain could've probably conjured up something more hardcore for a 3 minute wank, if he really has to.
If you can draw or have the passion to do so, then use it to create worlds with characters that interact with eachother, etc, or just draw characters you like. Don't waste effort into dumb shit like this. Women are interesting, but not that interesting, it's worth looking into drawing male characters aswell, or writing stories.
I couldn't possibly fathom what the backstory for "Jessica" might be other than being a husk of a character for the creator to project his lonely desires onto. I'm just hoping that it's not too late for him, if he can change, it will be for good, but others choose the path of being friends with people who enable this kind of behaviour, and that just makes it worse. I'm glad that I'm not who I was when I was 14 or 15 for example. I think porn addiction genuinely gets old, if you're reasonable and a certain age, it's just not cool anymore really. When you're 12 or 14, watching porn is cool, because it feels like you're doing something adult or forbidden, but when you are actually an adult, you realize just how sad and pathetic it really is, and also how voyeuristic and disgusting it is. It's also a lot of preparation and overglorification of something that's not really that important.
I think under certain circumstances, sex should be apart of people's lives, and the only reasonable way it should is in the context of a relationship and with the desire to create children, but even in relationships, people can become sex addicted and I think the thing people need to realize is that sex isn't everything, it is apart of our lives but in a very unimportant and uninteresting way. Putting something like that into your creative hobbies or work is just not good for you. Weird sexual stuff should stay a secret as a whole, kept between 2 lovers or kept in the back of some guy's mind at night. If someone like him is okay showing people pornography he made on the internet then I hope he'd be okay with showing it to his family too. If not, then why? Why is that? Is it because you have shame? You absolutely should have shame, because you know what you're doing is wrong.
