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.
What the hell? There are people who don’t have toilet paper in their bathroom? Do you stick your dick in the bidet every time you had a piss?
