You'd think with her position of power, she'd be MORE sexual. But I do agree, as much as I think I'm the alpha male here, I probably give off a vibe of insecurity and I'm sure she picks up on it.
Wow... that is a guy thought if I ever heard one. Don't 'genderize' your wife. POWER is NOT an aphrodisiac... at least not to most people. Maybe if you are in non-emotional sexual encounters, or you are doing role playing and what not... but think about it... rape is an act of aggression... of POWER over another...
POWER has no business in the bedroom. It makes relating to one another on a vulnerable level completely unbalanced... truly... it just WON'T happen, unless someone forces it. It makes for horrible sex. (Again, unless you are role playing, etc., and then, it really isn't an imbalance because you've both agreed to it).
The kind of power you are referring to is sensing... the person in the R who determines whether there will even BE an R. The person who decides if they are going to emotionally engage or leave.
Can you even fathom the pressure on the person who is in this position? Would you want to be that person? Does that even sound like a healthy, balanced R to you? I personally want to be involved with someone who is equally vested in the R with me... not someone who I look to to RUN the R for me. Or not.
