How young should you be to masturbate?

personally i think ths should be left up to her so she can start to understand her body rather then just getting told what to do. she can explore herself and see what feels good for her and she ll know when shes readyto move on to pleasuring herself internally. I think you should just tell her that its okay to do but not nesciarily what to do? its up to you hun really, but do let her feel for herself
