Interesting ...I have purchased one for my daughter as she asked for one at 15. As it was an item I could order from Cotton On I thought what the hell.  She had started discussing not marrying or having children and focusing on her career and finding the right partner . And she had definitely been masturbating from a young age. I remember the rash and sore thrush stage and it took a good 4 months for me to realise she was hurting herself with the new skill.
