Just chiming in to say you're fine. The 34-year-old might be too immature, though.
You didn't say which country in Europe. I can't speak for all of them, but the ones I am familiar with, the dommes I know, ALL started in their mid to late 30s or even their 40s. It might be strange to hear of a domina starting so young, not you at all.
You're fine. I see many clients 20 years younger than me. No one makes me feel bad about that.
