Is it normal that i want to ask girls to kick me in the testicles?

I've been wanting to do this for more or less 1 year, really, I want a girl to kick me in the testicles, feel that humiliation and that the girl feel empowered, I discovered that it is a fetish called Ballbusting, it's just that instead of paying someone to do it, I want the situation to be something spontaneous and if the girl is amused by my pain, then what better way to kick me with everything she has, I have asked 6 girls so far, they all said no, the first was just confused, the second laughed, the third was scared xD she must have thought I wanted to do something to her, for which I apologized if I scared her, the fourth was confused, the fifth laughed a lot but in a way kind and the last one told me a resounding and cutting NO to which I apologized for the inconvenience, I thanked her for hers time and left, if you think it is normal, what would you recommend for a girl to accept? I am as kind as possible , I also want to clarify that, I do not like to scare them, that think that I will do something bad or like that, it just makes me ashamed and I feel that I approach them very suddenly.
If you come to tell me it's dangerous and blah blah blah, I know and accept the risk.
