Hi there. Congrats on your effort to get support and talk about it. You will find this forum to be EXTREMLY helpful and never judgemental. We are here bc we SI and need to relate with others. Post any time and youwill find the support you need. Stay safe. As for therapy my therapist does talk with me about my SI but he also doesnt say its bad, stop, dont do it. Him and I are trying together to find other ways to get the feeling i get from SI so I can replace it and once again wear shorts in hot weather as my site is my legs!! I wish you the very best and there are therapists who are willing to help and discuss SI, maybe think about finding one to better suit all your needs.
Take Care.
