I had an experience where I depicted a piece of furniture, namely a footrest. You can see what it looked like here:

In my opinion, it doesn't evoke any negative feelings, such as a sense of humiliation or anything of the sort. I think the shade of feelings that arise depends on what's going on in a woman's head, what actions or perception ideas she personally associates with it.
Personally, I believe that there's nothing wrong or humiliating in using female forms to create furniture or depict furniture with a live person. It's important not to forget that men can also depict furniture pieces. I think that the female body is usually more graceful (when it comes to imbuing furniture with female forms), which is why Stanley Kubrick used this form in his film.
I would be happy to furnish my home with sexual furniture - using both male and female forms, as well as the form of sexual intercourse between a man and a woman. I see it as very sexual and creating a harmonious atmosphere.
