Men, do you worry your girlfriend/wife will have an easier time finding additional partners than you?

My girlfriend and I have been together for a year now. When we met, she had 2 casual partners, and now she has one who she hasn’t seen to often through the pandemic. We are each other’s primary partners (though we may not always subscribe to hierarchical non-monogamy). Now that we are both about to be vaccinated and the prospect of meeting new people seems safer, I am worried she is going to have an easier time than I will meeting new partners, mainly because most women I match with on dating apps are not okay with the fact that I am non-monogamous, but I assume the average man would not mind that a woman is in a relationship already, particularly if they aren’t looking for something serious.

Can anyone else relate to this?
