Totally normal! You’re fine! Don’t worry so much.Masturbating is a healthy and fun activity. Plus, it’s always better to learn as much as you can about your body to prepare for future sexual encounters. Practice makes perfect!
Some women have a vagina that “blushes” more noticeably so, yes, redness is normal as well. As long as there’s no itching or rash involved – just red from stimulation.
Carry on, soldier! 😉
