id say not the dildo yet but start off with one of the other two as theyre more flexible, thinner and less intimidating. i have the top one and love it :D. it goes in really easy and both sides feel great.
I've brought the first purple anal tool more than once. It's a nice toy and cheap too. Different thicknesses... so you can play and experiment. Double ended so versatile and also pretty looking.

Trust me the dildo is very slim and easy, definitely a starter toy
The first two look good, otherwise a tapered butt plug. I'd suggest not starting with anything phallic yet because it might be too much for her to handle.
