Well im 22...I had sex for the first time in 9th grade when I was 15. Do I wish I would have waited ...YES...but I got you girl...I know where you're coming from...always use protection...make sure this is what YOU want. Get on birth control for at least a month before you have sex. I would shave...just because ...u know how people are in high school...people talk...so unless your cool with people ..maybe finding out and laughing..id shave...itches..when it grows back tho...I prefer to shave....I like it...some don't tho...its up to you...But just please...make sure this is what YOU want!!!
