Sir,
THANK YOU for your observations and concern regarding this kind of behavior. as a fairly new sub myself, i have experienced this kind of agressive, tactless approach by several Doms. it is poor etiquette and irresponsible behavior. like doing brain surgery with a sledge hammer.
Doms need to realize that a new sub is still trying to discover their true identity and role in this community. often you are unsure of yourself as this is truly "uncharted territory." if you are also young and less experienced in life, this can make you even more vulnerable and fragile. an approach like this is terrifying and confusing for a sub at this stage of self-discovery and may scare them off completely.
Doms need to understand the power that they hold and do so with responsibility and honor. this kind of verbage and stance with a young, green sub is inexcusable and shows a lack of understanding of what is key to build a good D/s relationship... trust.
