If it's inhibiting you in any way, it's worth the discussion. If anything it would be worth it to hear your T to tell you that there's nothing to be ashamed of.

Here's a thought, what if telling her makes you feel better? It won't 'heal' the transference but odds are it will help to relive the pressure behind it and if your T is good, it will help you to uncover something about yourself and your own needs, that perhaps you didn't see before.

In other words, go for it! You'll be fine.
