Something I've learned is that women are far less respectful of men's privacy than women's privacy. Probably because men are typically considered to be the "less bashful" sex, and so their privacy is less important.

I've never had a girl tease my penis size, but I've had MULTIPLE girls volunteer information about the size of their exes entirely unsolicited.

If you have a little weenie and a girl has ever seen it, chances are other people have been told about it and now know. Do with that what you will.
