My parents don't know that i'm male physically but by heart and soul, i'm a female. how do i come out to my parents without hirting their sentiments?

Trans-sexual support: Your kind concern for them may help you find a way but some will depend on them too. Go slowly if necessary. Best to 1st find support for you - friend, teacher, therapist, Tx group or at least online forum. Then, sharing w/ parent(s) that you are dealing w/ a hard (non-specific maybe) issue and hope they will be able to stand by you through it. Small talks may be easier than a big one - patience!
