Of course. Your ear canal is full of sensitive nerve endings. You only need to touch it once or twice to learn how to avoid it. Use reasonable caution and you?ll be fine.
The hairs in your ear canal also offer feedback on what you?re doing. You might not be able to see what you?re doing but you can certainly feel what you?re doing.
It?s a ?total safety first? bit of advice but the reality is that done with care it?s very safe. People stick lenses on the eyeballs and don?t seem to worry about that too much. What it probably true is that poking cotton buds down is a bad idea they tend to push the wax further in rather than remove it.
