Sorry but you're pretty much the only person who gives a sensible answer. When i masturbate i think about girls kicking or hitting guys in their privates.
I know its really wierd but its like a fantasy and its really embarresing and i worry that its not normal. Is this normal? By the way i'm a teenaged girl.
Nothing wrong with it, though I certainly can't explain it. Honestly, it might be because you want to touch guys there.
Here's to hoping you're not a liar like nearly everyone else on this site.
If you go to youtube.com and type in the word "ballbusting" in the search engine you will see an endless list of videos on such a topic and links to many more on such a topic. So, it is nothing unusal, weird or anything to be embarrassed about. What you do in your privacy is your business, just keep it private.
