Breastfeeding Questions..

So I'm having some little issues with breastfeeding. I thought I had it under control since I breastfed my first for 6months with no problems. But this time around I seem to be feeling more pain when breastfeeding my 2 week old. He does pretty good on my left side but on my right side it seems to hurt alot more & he's making like smacking noises while breastfeeding on the right.. Is it because he's not latching on right?? Also has anyone had problems with baby choking during feedings? I'm kind stuck it's been forever since I had a newborn..
