Amsterdam or Paris bathhouse

This is my first trip overseas to Europe and I have never been in a bathhouse. I’m a 32 year old good looking red head, who has a long list of fetishes, and open to trying new things. I have friends that have recommended me to try out a bathhouse to have some fun. I generally would not have the self confidence to do this as I’ve always been a large man. I’ve lost quite a bit of weight but still struggle with confidence issues. Any bathhouses that would be recommended as having an open minded, safe clientele would be perfect. I may end up just buying an open front and back leather singlet to help with this haha.
