Nervous.

So I have a new donor and we have done pi once already but I am super insecure and now the new donor wants to meet during the middle of the day and I am super nervous to where I wanna back out. I hate my body and now I'm afraid he is gonna be so disgusted that he will back out. Plus I'm just starting let my partner see me naked in the light. I don't know how to mentally separate myself for this and I really want another baby but I can't seem to relax to let this happen.
