I feel jealous when other subs spoil my goddess

Idk how to explain this. My domme pretty much has a few regular subs that I know of. She isn't that famous so I know she's not super popular.

We have a weekly budget for drains and sometimes I tribute on top of it. Now, we have a dynamic where I fund her date nights and she loves to use me, make fun of me, and send me pics of the used condoms etc.

I enjoyed this dynamic because I felt special in this place. Like definitely a loser, but more like, her special loser, who stays a virgin for his goddess and gets cucked.

I don't have any confirmation so far, but I do feel jealous at the thought of other guys getting a chance to pay for her dates and being fincucked by her. I know it's not sensible to expect exclusivity, but I just wanted to vent my thoughts here.
