Years back my gf and I discussed my feelings around being polyamorous and she wasn't on board. She said she would be very open to possibly finding random 3rds or possibly a regular but she never follows through. Our sex life has been going downhill the last year for multiple reasons, but she continues to talk about how fun it would be. She tells me about women she finds attractive regularly and how she gets hit on. I've suggested finding groups or outings. Maybe she gives her number to a girl she likes or we go out and try our luck, but nothing ever comes of it or there's an excuse. I rarely bring it up outside of a remark about a girl we both find attractive. Maybe she just says it to keep me interested. Maybe she wants to cheat? She's made comments how she wouldn't be upset if a specific female coworker just made out with her. I told he that would do be considered cheating even though we've fantasized about it.

I don't know....I really like exploring and doing things outside of my comfort zone. I like to experiment with my partner but even that is usually a rarity. Once in a while we'll push the envelope together and then it could be months or longer before we step away from the standard sexual practices. I know it's a big step and so I don't push it. It's her body and her decision but I also want her to accept the part of her that says "she wants this". I want her to not be scared of trying what she says her body wants to do, but after 4 years I'm starting to think it's just a ploy?

Thanks for any advice.
