It is striking that in the history of ideas and development, the figures associated with love dolls are almost exclusively female. There are certainly several reasons for this. The stories in question were invented or retold by men. Not in all eras were women allowed to openly and publicly think up artificial love partners and to speak or write about them.
Of course, one wonders why, for example, there is hardly any talk of artificial young men, although boy love was so widespread in ancient Greece. Maybe these stories never existed, but maybe they existed and were later marginalized and eliminated. Maybe there wasn’t much interest in them in later eras either, so they didn’t find their way into male sex dolls and the media. All in all, the same applies to artificial love servants as to Eros in art: it is the men who describe, sing, draw, paint and create the girls and women. It’s a man’s world, and at its center is the ideal of a man from a woman.
Nonviolent sexuality does take place in prisons. However, it is not always desirable when it comes to lifelike sex doll orientation, the choice of sexual means and the choice of partners. Power structures can also play a role, for example in relationships with guards. So the restriction of freedom takes place in many ways.
So the way you can suffer from it is very context dependent. Of course, it also depends on the type of sex doll, whether there is free access, whether the sexes are separated, etc. As a rule, men and women are physically separated, but not everywhere and not always.
For example, in the Billwerder men’s prison in Hamburg, there is a protected area for women, and in the Limmattal prison in Dietikon ZH, certain inmates of different sexes eat together. The most difficult situation is probably the solitary confinement, where there are hardly any opportunities for the prisoner.
