FEET...on a sexual matter🤔

Girrrrrls, how many of you have been or currently are in a relationship with a man or woman with feet fetish?

If so, i would love you to tell me how was it, a brief would be enough🙈. Im asking cuz my current SO has it, which i dont see abnormal at all, though he tends to be ashamed of it( stupid,stigma). He has explain what it means and implies in a sexual way to him and in general, but i feel like experiences would help me to completely understand it. I kinda love him, and i want to make him feel more comfortable about it ( and explore it a bit😅👉👈)...at least around me💗🤔
