My wife (f25) and I (nb26) have a happy, monogamous relationship. Or so we believe. Romantically we are completely set on staying with only each other, but we have different sexual desires.

We recently discovered that she has a bit of an aversion to penises (makes so much sense looking back now lol) and I'm a trans person born with a penis. I am Pan and am aroused by all genitalia, and she is somewhat attracted to or curious at the least to vaginas.

We've done a lot of communicating and feel like our sex life just isn't really it anymore. We still want sexual experiences and MAY be open to introducing others to fill those sexual gaps. Our romantic relationship is our top priority so if things are even in danger of becoming messy, we're shutting that down.

Is there a type of "sexuality" or dynamic that this could be labeled as? It doesn't seem like Polyamory and Polysexual have the same meaning that Aromantic and Asexual do. I'd like to google some other instances just like this so I can get some advice. Or if anyone can help us out here, please!

If anyone is worried about if we're ready for something like this... valid, I know it can complicate things. We talked about it this morning and she said enthusiastically, "I'm gonna find you a dick to suck" and I've always been aroused by the idea of her having sex with others. So we are both at least on the same page with this.

Biggest questions:

1. What are some guidelines we can set to avoid crossing any lines we can't uncross?

2. How should we look for these helpers? Should it be strangers or people we know?

3. Is there a "label" for being monogamous but sexually open? Not important, I just wanna know lol.
