Quick bump-
I was 13 for masturbating to an orgasm, and became addicted to it.
I was 14 when I learned how to really use the water in the tub, or the jets on a hot tub.
I was 14ish for my first kiss.
I was 15 when I was first fingered, though it was anal on accident, and wasn't comfortable
at all.
I was 17 when I lost it, got fingered the proper way, had a guy go down on me, did accidental anal, and did a blow job.
I was 25 when I accidently swollowed. Yeah, I'm not into that. Wasn't bad, just tasted really gross to me for about 4 hours afterwards.
