Afraid to have , what do I do?

First of all, calm down. It really is true that size doesn't matter as long as you know how to use it. I've been with a guy that was on the larger size and he didn't know how to use it, so I didn't enjoy it...and then i've been with a guy that was on the smaller size and he was the best lover i've ever had. There is not way to fix this. You just need to build some confidence in yourself. Remember...the is only 4-6 inches long so you don't need any more than that.
