1. Yes, without a question.
I don't think i'm alone with it but i dislike how in the majority of scenes most of the production's focus is on the cum drooling out and as a result we get fake cum, and cumshots where the guy only has the tip of his dick inside the girl. Not to mention those scenes where the guy just jerks off either the tip barely in or completely out and puts it inside for the pop (sure it must have been a long shoot and probably is not his fault, rather the long hours, but that suggests that the pussy is not that good, whether it is true or not).
I'm not saying that a healthy load drooling out isn't hot, but movies tend to tunnel vision on it and other things suffer for it.
In some subconscious level i like to imagine myself being in the guys place while he fucks those lovely ladies and i would cum deep inside, because that's what feels good. Having a camera cut and fake cum flowing out of the girl's pussy breaks that fantasy.
2. I guess this is similar to the cgi vs practical effects debate for hollywood movies. I'm sure we'll get to a point where it will be affordable to use proper cgi in porn movies or some really realistic fake cum with some some release device in the girls vagina so you would be able to do totally real looking creampie scenes, but i think it all comes down to one thing: knowing that they did the work. And by that i mean the guy properly fucked the girl and busted a huge load inside here, because how insanely good it felt.
