Turning taboos into conversations and prejudice into connection.

About me

I started out studying psychology. Then I heard about menstrual education on a podcast, fell for it completely, and never looked back.

Today I educate young people about sexuality through trips, trainings, an online community, a podcast and even a clothing collection. What drives me is making it easier to talk about the things we were taught to keep quiet. Next, I want to bring this work to more schools, youth organisations and international projects.

Work that gets people talking

Travel · 2022–present

Erotic, Feminist & Queer Trips

I organise, curate and accompany small-group trips that explore a city through sexuality, feminism and its queer community. Every museum, talk and experience is chosen around the trip's theme.

Feminist Hen & Birthday Parties

I organise feminist hen parties and birthday parties. They celebrate the person of the day and their friends with activities on pleasure, bodies and relationships, in place of the usual clichés.

Building Boundaries and Breaking Taboos

I planned and facilitated a 5-day training course on sex education for 21 participants from 8 countries, and produced a toolkit so they could take the methods home.

Testimonials

In their words

Foi uma experiência única! Até agora, acredito que a Mariana seja a única na Europa a organizar este tipo de viagens (…) Recomendo para quem quer explorar a sua sexualidade ou, pelo menos, conhecer uma cidade e a sua cultura numa perspectiva mais erótica.

Traveller · Amsterdam trip

Foi uma viagem muito especial para mim, cheia de novas aprendizagens, reflexões e experiências (…) foram momentos incríveis que recomendo vivamente, todos cuidadosamente escolhidos de acordo com a temática da viagem!

Traveller · Amsterdam trip

Recomendo vivamente a todas as mulheres empoderadas. Irei novamente, assim que houver possibilidade e disponibilidade. Obrigada Mariana, foi Top!

Traveller · Barcelona trip

Estar nestas sessões foi muito melhor do que pensava, tudo o que é falado é imensamente importante, sinto até que devia ser lecionado em escolas por exemplo! Acho que todas as pessoas deviam passar por algumas sessões contigo e aprenderiam muito! (…) Com a nossa convidada e com as nossas conversas aprendi mais do que em todos os posts que tentei ler haha adorei mesmo a experiência e muito obrigada de coração!
