How and how often you use it will definitely determine the lifespan of a small boobs sex doll. Small tits sex dolls can be easily damaged and torn if you rough her/him or overuse it every night, especially in the vaginal part. That's why many small breast love dolls have removable vaginas or penises so they can be easily cleaned and replaced if that part is damaged. So use your flat chested sex doll gently and remove it after each use. Treat your lifelike sex dolls with care and respect.
