Any recommendations for hostel in Bali?
Male dorms if possible
There is a clothing optional villa (more so nudity encouraged), with dorm room (I think 3 bunk beds with shared bathroom/toilet) and several private bedrooms with ensuite bathrooms. They have private pool so you're encouraged to swim and sunbathe in nude. They also have common room where all guests can mingle (and more if you want, like, or don't mind being watched).
It's called L4ki Um4 Villa (change the '4' to 'a')
Guests are varied in age and body type, so it's a hit or miss, depends on your luck, but it's almost 100% gay visitors. I stayed there during early days of borders reopening post-covid, and luckily shared the dorm room with one hot guy and we had fun during the night.
