Well, this is in the context of people choosing to accept donations as an open-source developer. Taking donations requires opt-in, I would assume someone like you just wouldn't take them in the first place.
However, I'm sorry that they make you uncomfortable or even guilty, because that sounds to me like you think you don't deserve them. Which to me, is sad, because the other person making the donation definitely thinks you deserved it.
You can just ask to be pegged, many women are happy to do it nowadays.
