I send my therapist stuff that I find difficult to talk about via email or text, she responds in a very accepting way and that makes me feel able to talk about it in session. Once I feel accepted for whatever I say, I find myself naturally opening up. I approached the issue of sexuality this way and like your T she reacted in a very caring and non-judgemental way and was very proactive in how she engaged with the topic, even sharing a couple of things about herself (nothing current or unhelpful), I love my T too.
