My 22 year old daughter still lives at home.  I have heard her late at night masturbating, and having more orgasms than I ever had in one night. On the serious side my question is, is it normal for young women to masturbate and is there a downside? Also I would like to talk to her about it, But I do not know how to start up the conversation and what to say to her.  First of all I feel she is disrespecting her Father and I, by her doing it when we are home. Her Father is always asleep so he has never heard her and I am concerned that if he does he will be angry and will tell her to pack her bags and get out.  I want my daughter to understand, that it is not good to masturbate so often to where she can get addicted or ruin her relationship with her boyfriends.  As far as I know She has not had sex with a male only phone sex. I appreciate all the advice you give me.
