Therapy with LGBTQ couples doesn’t much differ from couples therapy with heterosexual couples. Stigma and being at a different stage of coming out though are factors that could act as stressors for LGBTQ partners.
At the individual level things might be a bit different. You might be feeling confused and anxious over your sexual orientation. You might be struggling with coming out and might feel lonely and isolated. You might be experiencing discrimination or might be struggling with homophobia (external or internalized). You might be having dysphoria around your gender identity and might be considering hormone replacement therapy or sex change so you can look more like how you feel inside.
Finding a knowledgeable and informed therapist can provide you with support and facilitate your transition to a more authentic life.
