In my experience, the people who attend erotic workshops are open enough to adventure into new territory to learn and grow in an area of life that makes many shy. Once you accept that sexuality is a wonderful part of life and nothing to be ashamed of, you can take advantage of the many people who have knowledge they are willing to share.
People who professionally lead sexual workshops are nearly always respectful and well aware that many people coming to learn are expanding their comfort zone. They are committed to the importance of consent and strive to make the experience both comfortable and expanding.
As for the participants themselves, I have been pleasantly surprised by the wide range of people I have seen attend from all classes, races, ages, etc.
If you are considering attending a workshop, find one that strikes your fancy on a topic you’d like to explore and enjoy.
