Just Started Masturbating

I'm 14 and I knew about masturbating when I was around 9 but I always felt weird trying it. Anyway, I just started it for real a few weeks ago and oh my god why didn't I do this sooner?? Just today I orgasmed 4 times. But at the same time I feel like it's weird for my age because most times when porn or sex or any type of sexual pleasure comes up in a conversation, all my friends act like it's super weird and "taboo" almost. So I don't know am I too young to be doing this, or is it normal?
