I am 5'3,and my calves are 13.3inch.but the thing is,I have slightly bowed legs from the knee down,so there is no meat lol in between and all of this is centered on the back as muscle(u know what I mean?).my girlfriends tell me they are too big,but I don't know,I'm scred to wear shorts because of this

Chances are they are fine, but the best thing would be to get someone to take a photo of you and a group of other people from the back. See if your legs look out of proportion compared with everyone else. I

It's next to impossible to judge your own legs yourself, as you always have a bad angle looking at them. And girls tend to have much smaller calves than guys do, so she may be a little prejudiced.
