Need to know what my body type i am?

Very important that i know this. Right so im 6'3 195lbs i dont gain fat quick but i do tend to gain a bit of fat round my hips and stomach when i eat sh"t.. I used to be really skinny with a bit of fat on my stomach but ive been bodybuilding for a while now so thats changed.. I tend to gain about 3kg of weight a month when body building, i always thought i was an ectomorph but i hope im not.
