Other. We both are aggressors, just at different times. We each have different strengths and areas of confidence sexually, and both of us use them to our full advantage!! He usually starts the action but I usually get the ideas happening and the toys going. He is great for starting the fantasies, I keep building on them. This makes for one heck of an amazing experience, every time!!
We both are pretty dominant. Each of us about different things though.
I'd say my husband is the more aggressive one. I'm an extremely indecisive person, so even when it comes to minor things like what to eat or which movie to watch, I'd rather let him be the decision maker.
