masterbation tips???

i need help. I normally rub my clit until i orgasm or at least I think I orgasmed. or I use the shower head. but my parents would not allow me to get a dildo or vibrator. and if i hid it they will

find it. I thought about buying a back massager thingy to use as a vibrator. if anyone has a diy dildo or vibrator idea please comment. also im not good at fingering myself do to the fact of I don't know where my finger goes and don't know where my gspot is. so i just stick with my clit.
