There are no concrete rules about having sex and getting waxed. I appreciate the women who are considerate enough not to have sex too close to the appointment time. You know how I hate coming in contact with your man's baby butter. We've discussed this. But after your wax, there is no set time for how long you need to wait. Even a veteran waxer should understand that the area will be a little tender after the service but should be ready to go in a few hours. But a virgin waxer should plan for things to be sensitive probably until the next day. Moral of the story; don't plan a hot and heavy date with a well endowed man the same day as your first Brazilian.
