This is a very common thing in many places. Take my high school as an example. When I first entered such a bathhouse, I did have a lot of resistance and even didn't want to go, but with the company of my roommate, I gradually got used to this way and didn't feel anything special.

In fact, public bathhouses are very tasty. In those places, there are always heated discussions, and students talk about everything. Here, many friends are like this, don't worry too much. Be sure to go to the bathhouse more often and tell yourself your habits.

Of course, if you really can't adapt, you can choose to go to the bathhouse when there are few people, or try to find a hidden corner, which will be better.
