It'll become an expensive piece of trash, you likely won't be able to stay hard using it because you'll be staring into lifeless eyes. For me to use that shit to get my monies worth, I'd have to stop masturbating for like 6 months plus to get a "reset" of my brains arousal triggers so that it would be arousing.
If you go from porn to this you'd have wasted your money, you won't be able to stay hard, I had problems staying hard when I went from porn to fucking a whore, I still made it to climax because I could get off on her noises, body heat, facial reactions, etc. A doll is going to be cold, lifeless, no moans and just staring back at you, you won't be able to stay hard, it will be a waste of money, if you could stay erect for that you might as well take up a job at a morgue and become a necrophile.
Don't waste your money. At some point I plan on stopping masturbating for a few months or so you get that "reset" then I'm going to start escortcelling, so I can "normalize" the sexuality of my brain somewhat, how else will I get my monies worth.
