In 2010, the World Association for Sexual Health (WAS) called on all its member organizations and all non-governmental organizations to celebrate World Health Day on September 4 in an effort to promote greater social awareness of sexual health throughout the world.

The first World Sexual Health Day was presented with the motto "Let's talk about it!" to begin to break fears and taboos surrounding sexuality. The theme of the DMSS 2010 was addressed in various forums around the world, many of them intergenerational discussions.

World Sexual Health Day 2011 focused on youth. "The sexual health of young people: "Youth's sexual health…shared rights and responsibilities".

The theme of the DMSS was a consequence of the creation of the WAS Youth Initiative and in the context of the International Year of Youth proclaimed by the United Nations.

Within the WAS, the different members of the Advisory Committee and the Youth Initiative Committee celebrated the day by organizing a wide range of activities in their countries of origin, from roundtable discussions to conferences and art exhibitions.

The central theme of World Sexual Health Day 2012 was diversity and minorities, "In a diverse world, sexual health for all." Around the world, activities to commemorate the 2012 DMSS made visible the realities of population groups, such as the elderly, transgender people, people living with disabilities and immigrants.
