If the quality is good, then the new sex doll will not be realized in a few weeks, sorry, this is just my personal opinion. I agree with Grimkins’ observation. All of this damage surrounds the play area, which should make you wonder why the type of lubricant used and how to clean it. You should post the lubricants and cleaning products you have been using.
Does the baby chemically react to your lubricants and / or cleaning products? That will be my first question. This is what I think. In my opinion, the lubricant or cleaner you are using is overly dry and / or reacts with TPE. I’ve seen damage like this (deterioration might be a better word), these old dolls have never been oiled or vaselined.
After just a few weeks, the doll will not look like this-makes me wonder if this is a bad TPE blend in the factory, maybe the plasticizer in the blend is insufficient. This is definitely not the result of overuse or forcibly opening the doll hole, I will contact the seller. Regardless of what you do, best wishes, but use TPE sex dolls solvents with caution, as other posters have said that doing so will make the problem worse rather than better.
