There is no simple answer to this question as it depends on a variety of factors including personal preferences and experiences.
Some people may believe that TPE sex dolls can definitely provide some level of satisfaction for those who use them, but they cannot completely replace a real partner.
While others find that sex dolls can be a fun and enjoyable alternative to real partners, they may believe that cheap sex dolls can be a viable alternative for those who are unable to have real sexual relationships.
Ultimately, the decision of whether or not to use a sex doll as a substitute for a real lover is up to the individual, the answer to this question is subjective.
