Lots of people suggesting going to dance classes together. I see why that would be suggested, I do want to remind anyone of how that might pan out, especially if you choose any partner dance, where men tend to lead and women follow.
As a beginner, it’s much easier to get started as a follower in any dance so that the chances are that their experience (her being much better than him) is likely to be reinforced. She will notice how much easier it is to dance with a partner who is already good, and he is likely to notice this too, no matter how tactfully she reacts.
However, if he does the work and gets the hang of it, he will find himself always with the pick of partners and even besieged as a leader. Even before he gets good, there will almost always be plenty of women ready and willing to dance with him.
She will find that it’s much more difficult to get really good as a follower and will get plenty of experience being grateful to get a dance from men who know they don't need to get better to secure a partner so tend to rest on their laurels.
Some dance scenes encourage beginners to learn both roles but even so… what I have outlined is the way it’s likely to pan out.
I don’t know what the answer is.
For me it’s been a mixture of choosing dance styles where mean and women routinely lead and follow and still have been so delighted to find a partner who can dance that I do a lot of travelling in order to facilitate dancing together.
Just sayin. Going to dance classes together may have unintended consequences
