Ho lawdy, I've been thinking about doing this for quite some time. As a young CD (and one who lives with parents during the summer) I've had to go out of my way to buy cosmetics and of course use them without my parents noticing, but I decided enough was enough after seeing just how little left I had in my bank accounts after paying for the books for next year's university course.
I decided to come out to my mum, and believe me I was positively ****ing myself in fear. Five minutes into the conversation and I knew I had done the right thing. She was supportive, kind, and knew exactly how I must have been feeling. I'm thankful to have such an open-minded mother (it helps that two of her best friends are a gay married couple I suppose!). As a very tall woman herself she mentioned having to go to transvestite shops to find shoes in her size when she was younger! My father took the news a little less well, but he seemed a lot more confused and unsure than angry--and still promised to support me the best he could.
Of course, its only to my parents, but still, its somewhere!
