Great Relationship, overthinking our sex

Hey! So I need your help gals......

So I have been in a relationship with this amazing guy for over a year, he’s like a dream and he thinks the world of me.

But our sex, something feels missing, like it’s still great, but idk, and he brought me a vibrator surprised me when I was blind folded which was sexy. I’m an over thinker so idk why I do this.

Work for me is super stressful atm, not making as much money as I would like. Which probably means when we hang out I can’t spend ya know. Any tips to motivate me or help me out or just reassure me like fuck idk.

Going through that over thinking mode and I don’t like it cause I know him and I are great
