Is sticking stuff up your butt ok?

Yes. But use common sense.

• Make sure it's clean.
• If it hurts, stop.
• Nothing sharp or rough.
• Nothing that could break off inside you.
• Nothing you'd be embarrassed to talk to a doctor about, just in case.

And remember that your anus does not produce its own lubricant. You will need to use a lubricant. (KY jelly works, as does mineral oil or petroleum jelly. Or you can buy a lubricant at larger drug stores or "adult toy" stores.)
