How to prevent infection in serodiscordant couple?

[123Hector123]

Hi, a couple of weeks I asked about estimation of positivity in my case after my partner discovered his positivity. After that passed almost 10 weeks. My results after two month are negative.
However, i read to much about exposure risk and related topics and case studies, still feel little bit nervous (not anxious) because this situation is potentialy risky. My parter is treated with ART and effectivity of treatment will be known after first test.
Now to my question. Is there some possibility of transmission when we use two preservatives (to prevent the one of them would fail). We are kissing very softly not deep, and we have only protected oral. I am insertive partner.

I know that all what I wrote is low or zero risk, but I ask about the cumulative risk in case of couple when the the contact is not only one encounter with positive partner.
Big thanks for answer.

DO NOT use two condoms for anal sex.  Using 2 condoms increases friction and increases the chances that both condoms will fail.  Use one good quality condom.

Kissing and protected oral are no risk at all to you.

You won't have any risk unless the condom (for anal) breaks, no matter how many times you have encounters with him.

Big thanks for answer! We used two condoms, and we always used high quality of condoms. We also use mich of lubricant, do you think it is still better use only one? I am afraid of broking only one condom, we use extra safe preservatives, but you know, it could be only written on the package :-(. Is there some other advices how to keep my self negative?

And I have another question, if he will be undetectable by time and condom will break, is it still risky for me?

The advice was very clear to use only one, and the explanation was provided. Your idea of using 2 is just fear based so is not scientific.
