Fetish Charms - For the Best Of Everything Fetish!

When we first started dating, my girlfriend somehow got the idea into her head that I had a very large penis.  I tried to dissuade her of that notion, telling her that it really wasn’t anything special (I didn’t know how big my cock was  and didn’t want to be humiliated if it turned out to be small.)  She wasn’t having any of it, and kept insisting that it must be huge.  Eventually I pulled it out for her.  She looked disappointed for a second, and then started giggling and said “Well I wasn’t expecting THAT.”  I was too embarrassed to ask her to explain what she meant, so could you guys tell me whether or not I have a cock that would make most girls giggle?
