I'm definitely attracted to masculine, dominant men. But a lot of masculine, dominant men are arrogant assholes, so I generally don't want their friendship, all I want is their dick.
In terms of power dynamics, I still don't know what I want sexually from women, even after all this time. My current partner is my best mate in the world, but she's very submissive in bed which means we rarely have sex because I often am too. Having said that, she's offered a few times to peg me, but I haven't let her yet.
