Your thoughts here have some grounding in my understanding of my early childhood experiences of sexuality. That being said, it's not easy to answer the question simply.
As Traveler mentioned elsewhere, if a dynamic combines intimidation and sexual feelings, it can work like a "power differential". However, trying to understand the relationship only in terms of power may miss an opportunity to accept that sexual feelings were present.
In my case, my brother's ability to intimidate me still eludes me sometimes. When I accept that uncomfortable sexual feelings were simply part of the reality in which we grew up, I relax a little. Focusing only on the power dynamic can make me overwhelmed with anger. While that’s understandable I can also miss the point that sexual feelings have a life of their own.
I guess what I'm trying to say is that because by unconsciously agreeing to taking on my brother's pain when he was molested during our childhood, I implicity denied my own sexuality. To accept that this happened, to resist going into denial, I have to also embrace the fact and reality that the intimidation could always be employed. Is this about power? In some ways yes. Yet iIn order to find our way back to accepting sexual feelings for what they are, in order to understand that we were both sexual beings damaged by his experience, I need to see a bigger picture of loss. For me, looking only at the power dynamic does not allow me to find a way to let go of the pain, once I’ve embraced it. Going through all of the other feelings, with fear and shame being at the top of the list, I feel empowered because I am no longer standing by in numb acceptance.
Hope you find these thoughts of help. Look forward to hearing your response in any case.
