No more silly than a lot of other topics here. It's asking for practical help, so on-topic posts would need to offer advice on the subject. And it's not a rare thing these days for guys to have their ears (and other things) pierced, so it's best they know how to do it safely to avoid things like infection. The reasons they do it is purely up to them, like to follow a crowd/trend, to look pretty with sparkly jewellery, to blatantly show off their wealth, or to attract a certain gender - it's their choice and they don't need to say why they are doing it.
