At least you are getting shot in appropriate parts. Two thoughts occur to me.
1. Learn to read paint coming in.
This can be fun. Get a teammate. Stand about 25-30 meters apart. You want there to be nothing between the two of you. You don't need a marker. He shoots at you once. You try to dodge. Let himn repeat this 5 times. Then, get your gun, let him put his down. Wash, rinse, repeat. You can be a ninja.
The kids I used to play with call it the orange game. This is great because at NPPL events they give away oranges that I could through at the back of their heads.
2. Make sure you aren't broadcasting by sticking you knee or foot or something out first, before your gun and face emerge. Your teammates can tell you about that iif you play against them. Learning to gel while playing some other team is good, but you have to play against players who will tell you everything you need to hear, sometimes, as well.
