There is no simple answer to this question, as there are a variety of factors to consider. For example, some people might argue that sex dolls are unrealistic because they do not resemble real-life humans. Others might say that they are realistic because they can be customized to look like any person the buyer desires. In general, it is fair to say that sex dolls are not as realistic as human partners, but they are becoming increasingly lifelike with each new generation of dolls.
