Hey Courtney (I love having a name to call you, just FYI, even if it’s not your real one).
So yes, you could ramp things up, there’s capsaicin rub which is the burning stuff from chillies, and it’s like satan’s cum on a bad day. But really, I’d recommend against it.
When you’re getting immune to something, when it’s no longer doing it for you, whether it’s menthol rub, fresh coffee, getting choked, or hardcore gangbang porn, you could always push for more. But that’s often not going to get you to a good place.
So the easy alternative is take a break.
Give yourself a month off from the menthol.
Try it again, and look, it works again, hurrah. And you don’t end up calling a doctor because you’ve drunk so much coffee you get breathing problems. True story.
Pro tip. You’re welcome.
