monogamy was a part of love that seduced me. I was a "nareux" in french, no equivalent in english, mean people discusted of sharing fluid with other.
Monogamy became a compromise between love and disgust. It is hard for me to walk over my discust. so it mean a lot to me.
After we have all a part of the other inside, this is why i find disgusting to exchange fluid with a third person.
If my SO cheat, then i'll be disgusted of her with other dude particle inside her, that i dont want inside me.
I find monogamy beautyful and I dont want to destroy it. It is a proof of love that you offer exclusivity to the other.
