Quick tip (specially for men living alone): have a small trash can in your bathroom

In many countries, toilet paper is meant to be flushed or people are used to a bidet. For a man, this could mean pretty much no reason to have a trash can near the toilet.

But if you plan on having people over, specially women as a date, have a little trash can with a plastic bag and a lid near your toilet. That's where your guest might dispose of a tampon, pad, cotton swabs, condom packaging, and similar items.

Make sure you have some toilet paper available even if you prefer a bidet, too - there are many times it could come in handy, and people might be shy to request it after using the toilet and realizing its not there.
