I want to watch my partners have sex but i don't want to be a part of it
I have two partners, I love them a lot and we've been together for a good few years. Our relationship is a little unbalanced in part due to my asexuality. It's something I've come to terms with and for the most part not a problem. They have sex with each other and I'm not really involved beyond teasing them.
The problem comes in that despite not wanting to participate, I have endless curiosity. I want to know what happens, to observe it, and to not have any pressure to join in. I have this dumb image in my head of reading a book or doing a crossword and just glancing over every now and then, but I also like the idea of quietly observing to catch every detail. Again, they would not be touching me at all.
TLDR, I'm asexual, my partners aren't. I want to watch my partners have sex but in like, the most passive way possible. Almost scientific study level of passive.
