it hurts, again but different?

Me and my boyfriend have been trying to have actual intercourse instead of just blow and hand jobs but it’s hard for me. We established the first obstacle is that i wasn’t wet enough and too tight. the second i think is the position. He has an upward curve and we like “g-whiz” position. I’m thinking i need to be flatter on the floor and he needs to be up more? lmk!
