Does size matter?

So I am 15 and me and my girlfriend are okay if anything happens when we're together, she has already gave me errections through boxers and said it was big but when she see's it I am worried because I am only 6.2 up and we are going to alone tomorrow...

night, so does size matter to girls?

Im 16 and that sounds like a decent size, Don't worrie about it ,

5.5 inches is the average size of an ADULT males penis when it is erect.

You're fine, don't worry about it.

Size does matter, but as long as your bigger than 4 inches she will feel it. average is 5.5 to 6 and im seventeen with 5.5. So your doing pretty good

you are really working with something.she was right!!!
