I have not personally donated eggs but feel different than most for a couple of reasons: I sold IVF supplies for 13 years, I heard some of the most amazing stories. Also, my daughter is adopted, not because of fertility issues but because she needed a home. I have never needed those eggs on a monthly basis so it would have been awesome if someone else could utilize them. I'm not that hung up on genetics and lineage.
If you feel at all uncomfortable or wrong, it is not for you and you shouldn't feel bad about that.
