You can also doing stroking exercises that elongate and grow girth of your penis.
And you can VERY CAREFULLY hang things from you dick to stretch it and make it bigger.
I don't recommend these things as I have said many times before that I get great mileage from girls and I have a small penis. I have girls offering me free service, girls begging me to take them to dinner, hang out with them etc and there is no way it is because of my sexual ability. It's all about personality. Girls love my personality. Girls love my attitude and they love my brain power. So, you don't need more than 6 inches to please a girl. The rest can be made up with exceptional abilities outside the bedroom.
Exit Question: How man Asian girls do you see with black guys?
Answer: Very few
Explanation: Penis size really doesn't matter to women. If it did, every Asian girl would be begging for a black boyfriend. And they would be marrying them left, right and centre. But they don't. Asian girls don't want black guys despite those guys, for the most part, having bigger dicks.
