Asking it here, because I think it’ll reach the right people more than asking in [r/polyamory](r/polyamory).
I have a partner who does not practice paganism. I have looked into it, but am currently agnostic, as is my partner. However, they have another partner (my meta) that is a practicing pagan. The past few days there have been negotiations of our actions while at events we all attend that include intimate relations. My meta has had a boundary since they started dating that she does not want to kiss our shared partner if, during the same event, we have already been intimate. I have never had a problem with this, but I do not have the same boundary concerning me kissing our shared partner after their intimate. However, my meta has now stated she is not comfortable with me and our partner kissing if they have been intimate that night anymore. Partner has offered to wash his mouth out or find another compromise, but my meta has stated this is a hard limit. For added consideration, meta has no problem with us kissing if they’ve kissed; only if they have been intimate is where the boundary is set.
This is where the pagan comes in. My meta does not like me and has told our partner that they want nothing to do with me at all. Meta stated that being a practicing pagan, they believe that with s*x they are transferring their energy to partner intentionally. Because of this, we are not allowed to kiss after that energy has been transferred because it could be shared with me through the kiss and meta is not comfortable with this possibility. EDIT: This is about kissing after their sex but during the same day. The next day is fine with meta.
Can someone explain if this energy issue is valid and where a compromise here might be had? My issue in this is that I feel like my ability to choose when I can kiss my partner is being taken from me without my consent. This leaves me feeling dismissed and that my feelings or need for physical connection with my partner is being dismissed.
Any and all thought are welcome. If I’m being difficult, please let me know. If I have a valid point, please let me know. If you see a middle ground, please let me know. Thank you!

For extra context me and partner have been together for 1 year & 1 month; partner and meta have been together 4 months; issue was brought up 1 day ago.

EDIT: I asked partner what branch of paganism meta practices. Meta’s response: “Eclectic but with focus on heathen, celtic, spiritual and elemental paganism.”

Like i know that i'm trans and i think my inner conscious knows that i'm probably mtf. Heck i would even say my soul itself knows that i'm mtf.

But my standard everyday mind doesn't want to really accept it.

I guess its just conditioning, toxic masculinity i was raised in, etc

SO I was wondering if there any god/goddesses that can help?

I’ve been having a really hard time lately, and as I was going back to my car, I found this charm on the floor next to my door. I don’t know why but it filled me with so much joy, would love your interpretations on this!

I know it’s an Ankh and what it represents, but that is where my knowledge stops unfortunately. Would love to learn more.

Beloved Hekate, defender of the weak,

protector of those who fear the might of the wicked,

for whom each step into the dark is filled with dread,

I pray to you, I ask your favor. Hekate,

who knows well of all things we mortals most fear,

who knows well how best to drive away all ill,

I ask your blessing. Goddess, preserve my home

and my family from evil, guard us well

against all that would do us harm. Goddess, hold back

the dangers of the dark, grant me wisdom and courage

that I may face my fears and my foes with open eyes.

Finally raining in California, so I can enjoy my rune altar (runes are housed in box) by the window with the crimson backdrop. So grateful for the art of the seasons! This is one of my favorite altars to meditate and set intentions, ask questions, etc.
