"Binge and purge" is a recognisable pattern for lots of kinksters - you indulge, it builds up, things spiral, there is release, you feel shame, you run away - until it starts again. The hard thing to do is conquer that shame and not let yourself fall into the spiral again. But it's also immensely liberating - don't stop trying to defeat it. You shouldn't feel shame for being into spandex - it's part of you, and it deserves acceptance!
