I would also ask yourself how often and how long you work compared to this doctor. I think standard for nurses is 3-4 shifts per week. Doctors work much more than this and often have out of work responsibilities as well. The hourly rate is much closer than you make it out to be.
I think you may have the wrong perspective here. Sex isn’t a milestone or something to “be obtained.” If you go into an encounter trying to check a box then, you are setting yourself up to be disappointed. Sex is something fun that happens naturally between partners who are open and both have interest in sex. Focus on being happy with yourself (be a person that you would want to have sex with) and investing in your relationships.
