learning curve for girls slower?

i've been going to school on the east coast and have been surfing as much as i could on breaks back in california for almost 2 years, but it feels like my progress learning to surf is incredibly slow. is the learning curve for girls slower? i'm 5'6" 135 pounds and very athletic and active, and i surf a 7'6" trifin hybrid/egg board. my paddling is great, but the biggest hump i have to overcome is catching unbroken waves consistently and riding it down the face. usually i pop up too late and ride the wave once i'm down the face already. also, is it harder to catch bigger waves w/a 7'6" because the rocker is so low? i usually find that the nose of my board usually gets sunk under when catching bigger waves.
also, i just started shortboarding on a 6'8". how long does it take to get comfortable with it? and how deep do you need to duck dive to get past bigger wave sets? sometimes i get caught in the cycle and tossed backwards back into the wave.
lots of questions, i know, but the help is appreciated. thanks!
