Actually most porn is less enjoyable because, in truth, apart from those guys who specialize in monster cock porn, most porn stars are only somewhat, if at all, above average. I am jaded enough that I see through all the tricks of the trade used to create the illusion of monstrosity like the wide angle closeup and other complimentary angles, and smaller girls or guys on the receiving end.
But I do really get off on porn where the guys have big dicks that I can believe are actually close to mine in size. And surprise surprise, there is way more gay than straight porn of this type. I would assume that is because most guys have average dicks (duh) and care more that the chicks are hot (duh again), whereas gay porn is by its nature more phallocentric. So I spend a fair amount of time sorting through bunk to actually find straight porn with big cocks fucking hot chicks. Thankfully, I'm a little bit bi (hence the 10% gay), so I can enjoy much of the more readily available big-dick gay porn. The irony of the situation is that although I am much more attracted to females in general, I end up watching substantially more gay porn. Being able to identify with the guy doing the penetrating is simply the most important part of getting off to porn for me.
