I've been with my nesting partner 2 years, and something I know very well about them is that they value and pursue new experiences, experimentation, and novelty in their sex life. I know it's completely normal for someone's sex drive to fluctuate based on people they're with, and for people to be more attracted to some people than others.

However, emotionally, this hurts. I feel less desired and less exciting than my partner's other sexual partners. It seems like they rarely want to have sex or do kink with me - I ask and make myself available - but if one of their sexual or kink partners is in town, they are suddenly very down for sex and kink. It's like they take advantage of opportunities they don't always have, but when it comes to me, who is always available, I'm old news, or not as exciting to play with because I'm always an option.

I'm sure some of this is my own perception, but it does hurt knowing they're having sex and doing kink with other people when they're rarely doing it with me. How do I deal with this feeling of inadequacy?
