The article presents a project of the workshop dedicated to lesbian, gay and bisexual adults. It is an affirmative workshop aimed at strengthening the integration of non-heterosexuality with the whole individual’s identity. The identity formation of LGB people is a significant developmental process, its optimal course can be a protective factor against detrimental effects of the minority stress. The workshop is grounded on the theory of narrative identity, however, it also refers to stage models of sexual identity development. The paper describes the theoretical assumptions and the plan of workshop. Its main part is an exercise based on drawing by participants their life lines, which is a widely used method in the art therapy. These drawings are to illustrate significant events associated with discovering and disclosing their sexual orientations. Then, participants tell their life-stories. The method is aimed at: 1) stimulation of narrative processing and autobiographical reasoning, processes enabling the inclusion of minority experiences in the personal life-stories; 2) identification of individual and social resources which can be used to cope with minority stress. Predicted and observed benefits and limitations, obtained during two editions of the workshop, have been discussed. The method can be used as a start-up of further meeting of a support group or a personal development group as well as a single strengthening experience which can complement the individual therapy.
