13 female, I often masturbate but when I try to put a dildo in my vagina I can't. I use lube and I'm still a virgin.
Your p***y will be tight try to rub your clitoris,you will get wet then try to insert your dildo,try massaging your breasts and nipples this will help you get turned on
Try masterbating to porn this will get your p***y wet,then you can put your dildo up
Start with something smaller. Stick a marker in and work your way up
