I think I am somewhere in between. I never wanted the responsibility of an "alpha". I'm more of the type who wants to go off and do my own thing. I do get very angry/aggressive if my feel like someone is on my case, riding me ( in a non-sexy way ).

Still, I feel comfortable with women telling me what to do. I think I could be happy in relationship that functioned like a modern vanilla relationship with a lot of bidirectional feedback/consideration, but when it came time to make a solid decision my GF would wear the pants. It would be interested to try such an arrangement out where how things worked out were explicitly stated at the beginning and I felt reassured that despite being "beta" to her "alpha" I would still be respected and wanted.
