It's really important that you learn to be safe. I realise that you're never ever going to use a dick that small but still it pays to be educated, just in case anybody ever asks you a question.
It's important that we all know what we're doing, or not doing in your case.
So I thought we'd do a little bit of a demonstration.
Now unfortunately I just wasn't able to find a real person with a dick as small as yours and I don't really want to touch yours, so I brought my little friend DingDing to help.
