Hands have zero cost attached to them, and most people have at least one at their disposal. Hands are not intimidating, and they can be used no matter what type of genitals you have. Using a toothbrush handle? You can use your fingers to figure out which, if any, orifices you're comfortable having penetrated, or if you'd prefer the stimulation stay on the exterior parts of your genitals. Also, make sure that different things you can masturbate with besides a dildo item you're using is yours only and not a shared item. Or you're someone who wants to wait to have partnered sex, or doesn't want partnered sex at all, but you still want to enjoy and explore your won body. You don't want to use anything with sharp edges or points on it, and you don't want anything that can shatter, splinter, or break off. Now, for a bonus question, can you tell me: You can also experiment to see if you enjoy simultaneous internal and external stimulation.
