I respectfully disagree with fosjoh.
There are no exercises which will permanently increase the size of your penis. There is no cream, lotion, pill, ointment, vitamin or anything else which will do so, either.
Your penis size is genetically determined and it will end up whatever size it is meant to be, (just as a woman's breasts will).
If you choose to spend money on 'solutions' which advertise that they can help you, all you are doing is increasing the size of somebody else's wallet.
Save your money so you'll have something to spend on your date and learn how to make the most of what God gave you.
If the woman loves you, I can guarantee she won't care if your penis is 5 inches or 15 inches. And furthermore, that's a guarantee you won't have to pay for.
