Since 2018 we’ve been conducting a large-scale study of erotic fantasies. In the Netherlands and Belgium we’ve interviewed over 300 people about their fantasies, both inside a traveling caravan and live on stage during performances at festivals and theatres.

After collecting hundreds of fantasies, we published a book, Yes, please! (in Dutch), and created an exposition in Marres museum in Maastricht, the Netherlands. Now, in 2021, we’re expanding our study to include people from all over the world.

Are you interested in participating in our online study of erotic fantasies? (Scroll down to sign up!)

Through Project Yes, Please! we want to celebrate the erotic imagination and break the taboos surrounding our fantasies and sexuality. Want to help us do this, while having the opportunity to explore your fantasies and desires in-depth, and contribute to science?

We’d love to hear from you!

But first: what can you expect?

  • Interviews last around 30 minutes. We conduct the interviews in English, though it’s also possible to do the interview in Spanish or Italian. You’ll be asked questions about your erotic fantasies. Our aim is to explore and understand your fantasies (and the desires in them), and many people have told us they really enjoyed the opportunity to explore their fantasies in such depth!
  • You’ll be asked to (digitally) sign an informed consent form and fill out a brief questionnaire.
  • The interview audio will be recorded, transcribed and potentially, in the future, published in a book and/or online. However, all data will be handled anonymously and if we were to publish your fantasy this will not, in any way, be linked to your name. Any identifiable characteristics will be removed from the audio/text. We will not record the video.
