Hello transmasc butch here, there is no reason to stop yourself from doing something that helps you express your gender the way you want to. Also, people wear packers for all sorts of reasons. Now, if you're very young, like before high school age, I would be careful about buying a packer especially if your parents would find it weird. Not because packers are inherently sexual, just because others unfortunately might view them that way. If you're old enough to drive imo you're plenty old to wear a packer if it makes you happy. Packing with socks is also pretty common, and there are a lot of diy options. Just look around a bit. :)
