Be careful and use anything you want, plaxtic bottle, cucumber, banana, zuchini, squash, tool handle, flashlight, hairbrush, look around your house for anything with the right shape and no edges to hurt yourself on then just be careful and don’t insert anything unsanitary or that can cut or rip you.
Ummmm sweetie, I really don’t think that you should be using items found around the house as sex toys. That is not really sanitary and just sounds disgusting. Why don’t you shop for a proper toy, they have some good sites out there if you are embrassed to do it in person. A sex toy might even be a lil more pleasuable than an banana or cucumber. You can get toys that vibrate etc. If you are going to use household items please throw them away when done, please don’t put that banana or cucumber back in the refrigator!!!!
