How likely is this?

I was chatting with a friend about our kinks and she was interested in how finding people who are also into fisting works when I told her about this kink. This made me realise I have a strangely high percentage of sexual partners who are into fisting. 4 out of the 10 people I've been with have wanted me to fist them vaginally. The reciprocation is a bit higher where 6 of the 10 wanted to fist me analy as well, but that's less surprising to me as all my sexual partners have been very queer. There has to be an element kfbias towards exploring different things within my social circles, but it still seems like 40% is a strangely high number for someone who's never looked out for people into this before having sex with someone.

How has this experience been for other people on this sub?
