I relate to your post. Although I agree with what the others said about it being possible for there to parental transference onto a T of any gender, I think for some people, it's much more likely to happen with one specific gender. I, for example, have never experienced paternal transference with anyone, yet I also experienced maternal transference to various figures from a young age. Due to the nature of my trauma experiences, I don't feel able to work with a male therapist (at least not yet), so that's why I've stuck with female T's and pdocs (with one exception for family therapy with male T who was great and I didn't have transference with). It seems like you might want to try having a male T because you are highly susceptible to the maternal transference. I think that's a wise idea. The worst that could happen is that you find yourself having transference with the male T - and it sounds like that's a certainty with a female T, so you might as well try.

As for secure attachment healing the void inside you where a mother should be (my own description for how it feels for me), that was not my experience. I was/am securely attached to my previous long-term T of 12 years, but that didn't "fix" me. Unfortunately, the security of that attachment does not seem to affect me now that I've moved away from her (I can still call her and see her when I visit). The longing that had become muted over time as a result of our relationship is back. So I guess what I'm saying is that I'd be cautious about hoping that a relationship that by its very nature must be limited in time and scope can actually heal this issue. However, that's just my opinion based on my own experience, so please take with a grain of salt.
