I know you were addressing the question to butches, but if I may add my two cents...I find that giving head to my partners that have strapped to be a huge turn on for me. And, for my partners, it has been an erotic and fulfilling experience for them. But I can only base my opinion on my own experiences. You said you partner is sexually shy, so perhaps this is something she would enjoy or that she wants to try, but has difficulty expressing it or asking for it. I think your best course would be to discuss it with her and, if she is willing, to give it a go!
