I found out I was donor conceived at the age of 35, 15 years ago. I put a post up primarily looking for my donor. Little did I know that I have a half sibling out there. My sister saw my post and contacted me. We both submitted a DNA test to Family Tree DNA. Turns out we are a match! We've been chatting on the phone for 2 weeks now and while there is some sense of being awkward (we've discovered each other when in our 40's), overall the communication feels natural. None of this would have happened if not for the DSR and Wendy's help.  

****Update****
We've now discovered 4 more siblings and we have unlocked our donor's identify.  Not sharing here, but if you are a sibling, please contact me!
