I will give you warning before you read this. I am not purposely trying to hurt your feelings, but you need a reality check and I am dead serious about this.
Of course it looks like you're packing heat, you're only 4'11 and 145 pounds, making you obese. Even if you have a LOT of muscle, there is no way a girl who is 14 years old and 4'11 should be 145 pounds. I am 5'2, 20 years old and the healthy weight range for my height is 105-125 pounds. You need to talk to your parents about losing weight, at the age+weight that you're at, you're only going to get fatter if you don't make a drastic life change. It may sound harsh, but the food you're eating and the exercise you're not getting enough of is going to cause significant health problems down the road.
There are slang terms for the bulge you're dealing with: FUPA (fat upper pubic area) and gunt (gut + you know what), and the only remedy is overall weight loss, some people are more 'padded', but you have a good 30 pounds to lose. Google those terms, you'll find exactly what you're looking for...and probably people who look a lot like you.
It doesn't show like that though. I know what a camel toe is and that is definatly not like that.
Wearr loose clothing it happens when clothes r too tight im overveight and mine did that.. ur mound will be biger then skinier girls its called a cameltoe when it shows like that
