After a year of living together and fully monogamous, I've realized that it's a huge issue that could even end the relationship. Im very kinky and good at it (I know it sounds so braggy dorky and stupid) but I've always had good comments, good connection, very wild and fun sex of different kinds. My gf is VERY boring in sex, it's painful to say so and she's adorable and everything else is perfect with us, but she's so vanilla, she likes one position and everything else is weird or painful, she's more than satisfied with sex once a week TOPS, while I want/need it once a day... It's really driving me crazy.Im obviously not going to push her and put any kind of pressure on her if she knows what she wants and she's happy like that, but I feel like there's a thin line where I also have the right to be happy with my sexlife. Has anyone had a similar scenario? How do you tell this to a girl and how realistic is to have a non-monogamous relationship for example? Any advice welcome. Thanks!

EDIT: I got a lot of understandable judgement based on my post history and lack of details in this post. I'll leave some answers here:

We both use Feeld to make friends, it's for that too, we recently moved together to a new city. we haven't use it for kinks or poly stuff, I've never cheated and I wouldn't do so without discussing non-monogamy with her first. Feeld did open my eyes to a whole other world of options that we could try tho. Feeld is a very positive community in general and it literally has the option to specify you're interested in friendship only. We like it because we're both in creative careers and among the queer communities there tends to be more creative and open minded people.

No, I didn't mean physical pain, I apologize for the lack of clarity of my description. She's not in pain, she just doesn't want to try anything, she finds it uncomfortable, she get's tired very quick. Doggy which is one of my favorites is the only one that is painful but she has never described it in detail to me she just dismisses it as simply not liking it at all. I've asked her, I've bought different products to make it easier on her, I always give her oral sex first which she does love and I always make her orgasm first so she's pleased and she always comes first and then we have sex, and it's just always the same...

No we haven't tried couples therapy or doctors for conditions she may have causing her discomfort but I think that's my next step.

I don't think I've been disrespectful or defensive towards anyone, if so I apologize. I'm really thankful for some of the insights and advices, and for your time, regardless of disagreements.
