Humiliate my self with an unflatettering penis pic.

So I have a lady that I was visiting this weekend. She is a swf and 34, quite honest upfront and abrupt. She and I have a mutual friend who was on a date this weekend. We were talking about dos and don'ts so this relationship could succeed for our friend. When she mentioned to him "don't send her a pic of your penis to her like when you sent one to me."

I was floored, well as the night wore on she showed us a pic of her vagina, I was thinking threesome, alas no. Any way I can't remember how, but she wound up asking for a pic of my penis. Now I am a white guy with a 6.5 inch cock that is pretty thick. I haven't had any complaints and I know its a good size.

Here is what I am thinking to humiliate my self, I will send her a pic of my barely erect, around three inch penis next to a ruler and all proud ask her what she thinks etc.

My pride is saying send her a full size one later.

Thoughts?
