Reddit mentions of O.b. ProComfort Normal 56 pcs

I'm using prices from Germany in the following.

Assuming:

• average use of 5 tampons a day during their period
  
• average length 7 days per period
  
• average of 12 periods per year
  
• periods from age 10 to 50 (40 years)
  we get a number of 16800 tampons used over a woman's lifetime (numbers from here)
  
  Assuming name-brand tampons (choosing "o.b. Tampon Pro Comfort 56er" from amazon.de) with a subscription, we arrive at a price of 3.61 Euro per 56 tampons (choosing the subscription here since it's easy to plan ahead in this regard). Thus we get a lifetime use of 300 packs a 3.61, or 1083 Euro. Of this amount, 19 percent or 172 Euros are value-added tax, amounting to 4.3 Euro per year. I suspect the numbers for the US will be similar, although of course the sales tax would be about half the percentage/amount.

Why would I? Should men pay for makeup, highheels and nail polish as well? Just because it's a "women only" expense? Man need 500kcal a day more? Have any women provided for this expense ever? I don't think so.
If there is a mutal interest like with birthcontrol I totally get it and I think most men have an open ear about it but making a drama about a hygene product that is used 3-5 days per month and costs about 5 bugs for a 56 pack? You got to be fucking kidding!
Tampons for reference
