Below has been my experience:
First lockdown - many MPAs were scared and followed government guidelines to stay at home. Some spas were still open in stealth mode. Sessions were cool because it was usually just you and the MPA in the whole spa. Services were pretty much the same as before except a few MPAs kept their mask on. I met some new faves during this time.
Second lockdown - most MPAs were not worried anymore and tired of all the government conditions. Even though spas were supposed to be closed, most were quietly open. Sessions weren't quite as private since there were often other MPAs there too. Services pretty much returned to normal.
Latest lockdown (i.e. stay at home) - similar to the first lockdown. MPAs are concerned about rising cases but more concerned about LE crackdowns and getting caught. As always, appointments are still available for good customers. I've only gone out a couple of times but the MPAs I saw were quite horny
, probably due to being cooped up at home.
