Here’s what i say to my students and i’m sharing it with you:

If your intention is to spend a great evening with your partner/wife/gf and not switch partners then it’s all good!

Now, if you wanna dance with others at some point, i recommend switching partners because you acquire a very important skill : adaptation. The struggle is real  at first but it gets easier over time… the wonderful thing is everyone is different so by dancing with many partners your lead or follow will become way more clearer and smoother … so i encourage you to continue and tolerate the discomfort 😉
