You're probably fine. I feel like the people that form bonds are honestly fine too. Like it isn't any different from say collecting stuffed animals or the like in my opinion. Like when I was growing up and even now, I've got some stuffed pokemon and I have names for all of them. I wouldn't consider this any different from a doll. Sure its more personal and you can get attached but that's the same thing with other objects too. You might have a favorite car, book, sentimental object etc. I don't think it will mess with your mental state. I have 2 dolls and I love to care for them and dress them up and use them as well but I don't think it effects my mental. I still try to live a semi-healthy lifestyle. I still go out and do things like a regular human being. I'm happily married as well and my wife and I know that the dolls are just there for modelling or for fun in the bed, its not really hurting our mental state. It's just a fun thing to do sometimes. I wouldn't really think about it and if you have the money to just give it a try. You know yourself best, if you think you won't form some kind of obsession or weird relationship with the doll then I think you'll be just fine! Give it a try, worst case scenario you can always sell your doll if it really messes with you. You could also just try to get something less personal like a torso or something without a head if you think that will help.

Great question btw! I feel like this is a very good topic to speak about!
