HOW YOU CAN WORK WITH US

On site & online

Couples
therapy

It is normal for love, relationships and partnerships to change over time. The initial infatuation often gives way to reproaches, arguments and resignation. Especially when children, a new job, illnesses or external relationships come along, there are challenges that often cannot be overcome alone.

We will be happy to advise you:
  • constant disputes
  • misunderstandings
  • thoughts of separation
  • affairs
  • and all relationship problems that cause stress.

Sexual therapy

Sexuality is often not discussed at all or not discussed enough in relationships. Especially when the body, the relationship and the desire changes. Everyday life, stress, sexual dysfunction, listlessness and ageing often influence the initial joy of one’s own and shared sexuality. We are here to support you.

We will be happy to advise you:
  • Lack of desire
  • Orgasm difficulties
  • Erectile dysfunction
  • Questions about pornography
  • sexual preferences and all questions about your sexuality
