XD i know random question but whatever lol
What type of sex toy is it? If it's a plain vibrator, you can turn it on and rub it around/on your clit, or insert it and hold it in/move it around with one hand while playing with your clit with the other, or use it on other sensitive areas of your body. Whatever feels good.
If it's a rabbit/combination type, turn it on, insert it and either leave it there or move it around/move your hips around.
If it's a male sex toy, I wouldn't know as I am a female.
You'll basically have to play around with it and find what really gets you excited.
Hope this helped. Enjoy!
you can trying lube to help with dryness and a pillow under ur hips for position.
