I visited the Szechenyi Thermal Bath with its beautiful outdoor pools - swimsuit required, and there were no signs of action.
Rudas Bath was silently consensual, but trying to find some privacy is difficult. I did have a quickly in the bathroom stall though.
If you are thinking of visiting, their locations and other details are available on the internet. I am sure you would take the opportunity to check their opening times and gender availability in the process.
I wish you all the best and have fun!
