For anyone who might not have noticed yet, there is currently a glitch that lets you shoot scenes without consuming stamina bars.
What worked for me is making sure my bars are filled enough to be able to shoot 2 scenes BEFORE the daily reset, and start shooting scenes after the daily reset happenned. When a girl is done with her scene, go to her page manually (top left menu, then tapping on the girl) instead of tapping on the notification.
Do not use any item to restore your bars, as it will most likely fix the glitch.
Devs said (on discord) that there won't be any bans for using this, as some players can't even fix it by using items.
Enjoy
