I don't really care who tickles me.
I also think it's a man's thing.
Not always, of course.
My boyfriend at the time always wished that another woman would tickle me.
He would have had more fun watching it than tickling it himself. :-D
I have very big feet myself as a woman.
However, I am also 6'5 tall.
In the course of my years I have noticed that it is very extreme.
Some like it, others don't.
But I wouldn't say that the majority is on big feet.
At least not in the area of foot eroticism, where I am mainly busy.
