Hiding Yourstash with a condom?

This is and idea ive heard numerous times, never tried it, haha, anyone here, not to sound gay but it sounds like a good idea, but would it scratch your dick. The way you do it is have a small amount in a bag, drop it into the end of a condom and unroll....??kiss-ass....

Why though ? just a regular plastic baggie would work the same no ? and with a lot less trouble attaining the weed when you wanna smoke it....
