I've been with my partner for the last 8 years, since we were both 17. Our relationship has always been very close - we came out together and dealt with a lot of intolerance in our small town, which I think forged a closer bond between us.
I care about her deeply, and want to keep the relationship going for as long as possible. But I also have a quite specific kink which she isn't into. I've tried discussing ways we might incorporate it, or ways we could work around it, but she's not interested. It's something that has become increasingly important to me, without which I think I will struggle to feel fulfilled.
AIBU to wish she'd be more open to this, or to consider asking for an arrangement in which other people might fulfil those needs?
