Like spermkiss said dump the bitch I have a small cock and if a woman ever told me that she'd be gone just be happy with What you have

All I can say is what Spermkiss says so well, that is forget that lady and move on. She is hollow, shallow and selfish, putting dick size before you as a person.
Such a lady is not worth your time and you deserve much better.

Dump the bitch! NOW! Any woman who'd say that to her beau is a fucking cunt who doesn't deserve your time or attention.

Now, to answer your question about penis enlargement, short of surgery it isn't possible. And surgery is expensive, risky and has mixed results. See the "Penis Enlargement Scams" article on this very site for more information on this. So learn to be happy with the penis you have because it's all you're ever going to get. And go out and find a different girlfriend who wil accept you as you are.
