It depends on a few things if i've thought about it first or if its a bit spontaneous . usually my hand / fingers . but a dildo if i want something inside me . but hair brush handle , electric tooth brush handle , blusher brush handle , pillow humping .
My fingers mostly and pillow humping
Ive had 6 toys in my lifetime but also have used: skillet handle, stuffed animal/doll, marker, towel, sheets, veg/fruit, curling iron, lint brush, hair brush
... fingers and pillow humping
I have a variety of sex toys but they mostly get used when we are playing together. Things like really big dildo becomes a big cock fantasy and flows into our role play. When alone and masturbating I always go for either my trusty bullet vibrator or my fingers.
