Female Masturbation... Fingering hurts? Am i too young? FEMALES ONLY

okay, well first off im thirteen and yess...i do masturbate...i first started in fifth grade at age eleven...iit was exciting and at the same time frightining...i thought i was this freak because no one else talked about it and no one had ever told me they did that not even the guyss...although its was pleasuring and wonderful...i felt weird for doing it because i started off with humping a teddy bears nose...and to top it off i watched porn...lesbian porn... although it was no nudity imm not a lesbian i was just afraid off what the human penis would look like...i was too scared to actually visit a pornsite and i was definitley afraid of my parents finding porn in the history or worse off cathcing me...i usually did this everyday after school when no one was home...i had this sensation that tired me it made me want to lay my head down and go to sleep...it made me want to scream out and curse...in sixth grade i continued this technique for only three times a week...and this year  my dad had bought this nutregena pore cleansing thing that vibrates and it has two modes...slow and super duper fast...i heard immature ppl talking about it at school and i decided it was time to try it...on a real pornsite...so i did and boy was it great...i loved it and i still use it i stopped watching lesbian porn when i stumbled upon a threesome video and the vibrator only took about twenty minutes for me to reach my maximum pleasure...i heard of fingering and i honestly want to trry it...but im too afraid that i might injure myself...i read online about this thing called a hymen...its this film on the inside of your vagina and it pops once you have sex or finger yourself...its said it was minimal bleeding and small pain...shooohhtt pain is pain and bleeding?? heck naw...i really want to pleasure myself to the max without putting myself in any pain whatsoever...so do you have any tips for first time penetration for me??
