LGBTQI is short for: Lesbian, Gay, Bisexual, Transgender, Intersex, Queer/Questioning, Interested.
There are many other forms and expressions of sexuality. The reason this initialism is used, is to indicate that there are people who ask questions, who are open to alternatives to hetero and male/female, and who as a result are ‘different’. What can be helpful with being different, is becoming aware, which obviously can be helpful in other domains of your life too. Otherwise, it can confuse you, agitate you or even make you feel sad having to feel different if you did not choose to be who you are and what you feel. Therapy can be a place for relfection, to become more aware and to seperate what feelings and thoughts are you and yours and which ones come from the outside world.
