My husband has a constant complex about the size of his dick. He constantly talks about it, asking me what size my exes were. If I don't want a cupcake for some reason, he starts saying that it's because he has a small dick.

It's not small at all, it's average, normal size, and I'm fine with it. I don't know how to explain to him that I'm not attracted to huge dicks, like in p0rn*h! What to do?
