This is probably a longer answer with more details than you need, but here you go:

I'd been seeing a female therapist (T1) for 6 years and often felt uncomfortable opening up to her, fearing what her reaction would be to certain things I shared, that she'd judge me. Pretty sure this was coming from some negative maternal transference, as I thought she'd respond like my mom would. I've also been seeing a male marriage counselor, and I've felt more comfortable opening up to him. However, I also have strong (mostly) paternal transference for him, but it's in more of an idealizing form, so positive feelings and attachment. But also, the thought of termination and not seeing him again is extremely painful for me.

I realized that my individual T wasn't really helping me with the attachment to MC, I think in part due to the negative maternal transference, but also maybe just her therapeutic style? So I sought out a different T to try to help me with that. I intentionally looked for a male T, figuring it would be easier to talk to him. I knew there was a risk of paternal (and/or erotic) transference occurring because of what happened with MC (and also a male authority figure or two in my past). BUT I also figured that if that did come up, it would be much easier to work through it with an individual T than trying to sort of work through it with a marriage counselor (though MC has worked with me on it the best he can while mostly staying within boundaries of marriage counseling).

I've now seen the new male T (T2) five times, and it's mostly been going well so far. I've felt able to open up to him more quickly, which I think is related to his gender. We had one conflict (financial policy related), and I immediately let him know I was unhappy about it, which I think I would have had more trouble doing if he was a female T. And we resolved it quickly (he fit me in for half-session to discuss it). It's too soon to tell for sure, and it also could be that his style is different from T1, along with his gender.

I definitely think it's worth trying a switch though, especially if you feel "stuck" with your current T (as I did with T1--on more stuff than just the MC transference, too).
