just to clarify a few points:

1.) I do not like to steal undies, I dont have a habbit to collect such trophies.
2.) I do not sniff just anyone's undies, I only choose those undies which owner is someone I have target.
3.)I appreciate nice looking undies, I enjoy the scent and imagine what the real thing smells like, I believed it is lust rather than a habbit of compulsive stealing or perverted act.
