well, like i say, if you've got your dick in your hand and ready to explode, i can't help you explain that one away, even if you cover yourself you'll still have a tent there, so yeah a lock on your door would work, but wouldn't that be more suspicious, lol, and for the "it still doesn't solve the fact you still have to rush for that button" you could keep your finger near the key so it looks like your "working" on something instead of watching, or something like that
