You also may find it helpful to start training as if you were new to chastity. Start at an hour or two a day and work your way up to give your body a chance to adapt.
When I started I either didn't get that advice or I ignored it (I don't remember which! lol). I wore it until it chaffed and stopped until it healed over and over again. Not recommended! lol
I find baby powder helpful, especially in the heat, but oil or cream may work better for you.
Good luck!
