Hi! I believe everyone has the right for decent relationships (with friends, family and partners) as it has tremendous influence in their quality of life. Many things influence the way people behave in relationships - I am here to help you explore what might be getting in the way of you getting the relationships you want. I work with all sorts of issues in relationships and sexual difficulties, and will offer you a non-judgmental environment while facilitating the therapeutic process for self-discovery and actualisation.
I help clients to deal with anxiety, conflict in the relationship, vaginismus, erectile dysfunction, rapid/delayed ejaculation, pain during sex, fear of sex, discomfort around sexual practices, sexual trauma, lack of pleasure during sex, communication issues, desire to change the dynamics of the relationship, change in circumstance, and more.
If you think your personal, sex and/or love life could use some improvement, I am here to help. In the case that any of the things I mentioned before resonated with you, or if the issues you are facing seem to fall into the same category as those I have mentioned, you can contact me to arrange an appointment.
Olá! Meu nome é Cássia e eu sou terapeuta especializada em problemas sexuais e de relacionamento. Se você acha que sua vida sexual e/ou amorosa poderia estar melhor, eu posso ajudar. Trabalho com problemas de relacionamento de todos os tipos, desde dificuldades em se relacionar, a conflitos no casal por conta de diferenças em crenças e valores; ajustes necessarios quando os indivíduos decidem abrir a relação, problemas sexuais diversos (como problemas de ereção, ejaculação rápida ou tardia, dor na relação, vaginismo) e diversos outros problemas que afastam as pessoas de terem uma vida sexual e amorosa plena.
