Am I the only one? Or is it too weird?

About a yr and a half ago my boyfriend and I went out for date-night. We had a few drinks and things got hot and heavy when we got home. Well skip forward and he's going down on me and is fingering me at the same time. I'm so turned on and wet that I don't realize how many fingers he's using. And next thing I know he slowly slips his fist into my vagina. It was a big shock but not painful.

I was even more turned on after he did this. Just having a diff sensation and that feeling of being full. I have a few gfs i talk to about sex with sometimes but i want to talk about fisting sometimes. Am i the only one who indulges in fisting? And is it a weird thing to like?
