I don't like being touched

Okay might sound obvious or stupid of a question but is it okay for someone to touch you if it's a family even though you really hate being touched and had made it clear that you don't like it. It's not even a bad touch more like hugging and kissing on the cheek from my family members yet it still makes me uncomfortable to the point that I physically can't even be near them without jumping or literally taking dramatic steps back that makes them call me dramatic and stuff.

One day, it was night time. It was a small party where the neighbors, one my family members female, literally touch me there. I'm serious not even a slight touch she did it two or three times before I literally started screaming but when I tried telling them she touched me down there they just said it was just a "joke" and it's okay cause she's a female.

Everyone seem to act like it's okay and just a simple joke even though I made it clear so many times that I don't like being touch yet they think I'm dramatic for it and just really hate even though I do it for literally everyone including family and teachers.

Is it really okay? I'm also a girl...
