am i the only one?

so this has happened on so many occasions i'll take a pic in my underwear and guys will say that i have a fat vagina. i've even had a few say it looks like i have a penis. i laughed the first couple of times but now it makes me uncomfortable. all my sisters have camel toes so i knew i was already different but is there anything significant about a "larger" vagina. also i'm very petite. only 100 lbs and 5'2"
