Seeing a different T while T is on break

My T is currently on leave until mid-end July, and I've been seeing a different T (used to be my group T) while he's gone. Thing is, this T was good as a group T because I only talked for 5 minutes top, but I really don't like how she does her sessions. She has said I could tell her what my main T does, and she'll try to follow it as best she can, but she's just not him and I don't have the same relationship with her. I have 3 sessions with her until my T is back, so I'm just going with the flow right now.

Anyway, the thing is I see her this Thursday, and something has happened this weekend that has really triggered me. I would be comfortable telling my actual T the situation, because we've already talked about sex before which is what this is about. I'm NOT comfortable talking to this T about it, but it's something I really need to talk about.

I'm not sure what to do about this, and I don't know how this T would react and help me process it. Do I wait until next month until my actual T comes back, and work through it myself? Or tell this T?

Another thing is my T would call my doctors and talk to them directly if I had an appointment coming up that I was very nervous about. I have one Thursday afternoon for getting some moles checked, and this is a situation I'd ask if he could help me with.

Does the gender of the T perhaps have a significance in terms of people you have known in life?

I think if you try to present things fresh not thinking okay how would I present this to my T, will this sub T be able to accept, just present it and let the T guide you.

Better to share with someone rather than bottle it up inside.

No, it's not the gender. I've shared it with both of my T's that I have a good relationship with, and one is female the other male. Sex issues are just extremely difficult for me to discuss, but I've been able to slowly share things over the past 2 years. I'll probably share it with my other T when I see her, and that way one of them knows. Thanks.

I ended up telling both of my T's about what had happened, because I felt like it would be more helpful than hiding it. My temporary T said she'll support me as much as possible for the 2 sessions that I have with her.
