And another perspective Islandgirl. I had a baby boy adopted at birth 14 years ago. I would be delighted if he decides to make contact in the future, and I think most birth mothers would be in this position, as it's something you have to live with for the rest of your life*.
It can be very emotionally draining on everyone though, and I would recommend using a third neutral party, or maybe a friend or relative, to provide a 'buffer zone' for the raw emotions. My ultimate dream is that one day he will decide to get in touch, and I would be thrilled if he just turned up unannounced on my doorstep ... but if I'm honest I don't think that sort of a 'shock reunion' is the best start to a new relationship for anybody. (I'm sure you wouldn't do that, but some people do - it is so easy to trace people nowadays).
Do you have someone you can talk things through with? Just making the decision to start to trace is a huge one. It is possible that you could learn, very quickly, that your birth parents have died. Are you prepared for such revelations? Some counselling could help you prepare yourself.
As a birth parent I can make it clear that I am happy to be traced ... by making sure I am as easily traceable as possible (which I have done). But it doesn't mean that the best way forward is a speedy and hasty one. Sometimes it takes a long time to trace relatives, and this period of time is a good opportunity to adapt and prepare yourself for the process.
Warmest wishes,
*I am in tears just writing this, and thinking back to painful memories and forward to hopes and dreams for the future. When I decided to register with NORCAP it took me about a month to summon up the strength to phone them, and then they sent me the wrong forms initially and it took me another month to work up to phoning them again.
