How should I ask my friend to Experiment with me?

Just tell her that you would like some advice on mastrubating and tell her you would like it if you could mastrubate together. After a while when your mastrubating together get her to finger you by getting her to stroke your clitoris and finger your vagina. You should get the most pleasurable feeling ever and this will help you discover what makes you feel good. Many people do this and not because their lesbians because their good friends. Also you can get an even better feeling by getting her to rub you with your pants on.
