When you are intimate with your significant other:
A: Are you vocal in some way? Maybe you are a Moaner. Perhaps you are a Talker who likes to express how you are feeling at that very moment. Maybe you are the dominate type who likes to give commands.
B: Are you completely silent or nearly Corpse like? Not vocal at all. Perhaps some lite to moderate elevated breathing.
Please tell me which describes you best!
What a lack of choice, I like to talk and communicate with a partner how do you know what you are doing is what they want unless of course they can't talk because of shrieks of ecstasy or my mouth is full.
