This is what happens when you try to mansplain tampons to women

A man on the internet, armed with little more than a giant ego, worked out precisely how many tampons women need each year, on average, based on a period he definitely doesn’t experience.

Sigh.

A Twitter user shared a screengrab of what appears to be a Facebook comment by a man detailing the average millimetres of blood a woman expends per period.

Sigh.

“Look at this f**king dweeb,” Twitter user Ash captioned the screengrab.

Women are quite annoyed that a man thought it appropriate to tell them how to period.

His numbers are in dispute.

His interactions with women is also in dispute.

There's also the question of access to sanitary products...

Period poverty, which is a lack of access to feminine hygiene products due to poverty impacts more than 1.2 billion women. Globally. Every year.

Everything is in dispute.

The mansplainer ‘splained it all with the following, and we have questions.

1. 'The average period is between 10-35ml of blood.'

Right. OK. So how does he know this? Does he experience a monthly visit from Mother Nature in order to come up with such a number?

2. 'Each tampon holds about 4ml, so 7 tampons per cycle.'

You wot?

3. 'Lets be generous and say 10 for those ladies with an extra juicy uterine lining.'

Few women refer to their uterine lining as ‘extra juicy'.

4. 'Nine periods per year = 90 tampons max.'

This of course assumes that all women bleed exactly the same average volume every single month.

5. 'You can get a 64 pack on amazon for £7.90 plus shipping. Buy two packs, save on shipping and have 128 tampons for the yea, that’s about £20 here or their for a years periods. [sic]'

This also assumes that tampons are the only form of sanitary products women use. It's not - there are sanitary pads, moon cups and period pants.

6. 'Cut down on your Starbucks venti frapps and stop whining. This isn’t a first world problem.'

No.

So where did he get his information?

Ohhh.
