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.
To go along with that, if you are adding one for having a lady friend over, you can have a container of individually sealed tampons or pads available. They will likely never need it but in the event that they do, you’ll have gone a long ways to making them more comfortable. When you first show them around your place, and mention the bathroom location, just casually mention that there is an SOS kit that has a few things like pads/tampons/etc in it and don’t be awkward about it.
