How to explain why you into suppositories fetish to other

I have active account on twitter to chatting about fetish and sex generally. Some times I discussing with some girls about suppositories fetish and they always say it is stranger things. And ask me how I am into this fetish and why, some time I faced difficulty to explain who I feeling about that and why I am into this.

I am interesting to insert suppositories to girls but usually I pay some money to accept that fetish. Have anyone idea about explaining that or faced that before?
