Sally Ride was the first American woman and first lesbian in space, first flying in 1983. Before she flew, NASA weren't really sure what a woman in space might need, so suggested providing her with 100 tampons. For a six day mission.
@vagina_museum Better that way, than another. The last time I've participated in so called "main stream social media" there were some men believing that one tampon for the whole period is enough...
I guess that this is a result of not openly talking about this topic. I was raised in a household without a father but with my mother and my sister (we even talked about the period during dinner). So talking about the period was totally normal for me. Only later I found out that many men find this topic very disturbing.
