Shoesession

Just curious to know if there has ever been a study done to find out what percentage of the population of the Earth cum in the shoes of their partner, be that men or women either as the givers or receivers?
One presumes it would be far higher for the percentage of men cumming in female partners shoes, but that is just me as a man presuming that.
Anyone know of any stats, a quick internet search drew a blank?
Also is it more common a practice in the East or West, North or South? I have nothing to back it up but from. What I see on porn sites it appears to be quite common to cum in strangers shoes in Asia as opposed to partners or close associates only in Europe and America. I have no data for this it is simply the impression that I get from what I see online but I could be totally wrong.
Any thoughts?

I sniff and lick on my partner’s heels

I Cum in and over my wife’s high heel shoes and boots all the time. She is fully aware of it too.

I lick, smell, fuck, and cum in my partner's shoes. She knows it, and just asks that I wipe them clean afterward. She wears them for me, does shoeplay teasing, shoejobs, and wears them for me during sex. She is fully onboard with my shoe kink, and I've never been happier about it.

My partner has a large and lovely shoe collection and is happy to wear shoes for sex and shoejobs and will also jerk me off with and into her shoes .
But ...I never jerk myself off with any of her shoes - it just doesn't press my buttons . I have a massive fetish for jerking with my secretary's shoes (she doesn't know) but that taboo feeling just isn't there with my wifes.

My partner has a huge heel collection. I use to when we first met, but now I don’t. Loses the excitement. Sadly

I cummed on my ex's boots before.

I’ve enjoyed all my past partners heels to the fullest I could

Now I pray for encounters where I can get a bit of alone time with sister in-laws heels but it hasn’t happened yet
