One sets things up to look good, one does not set things up to feel good. If your dick knocks your knees and you are fucking someone with a frame like a bag of spanners you can achieve angles that someone with a more conventionally sized penis and someone that has some cushion... I can't even say just the tip as that would be impressive.
Spin it another way (or don't as that would be uncomfortable). When teaching firearms handling a thing that is done is to get someone to hold out their arm outstretched, possibly with a weight, and seeing how that is really quite hard. Now imagine the same with someone holding their leg over their head for 5 minutes while being pumped. If you are going to expect, or create, such angles at which things may not comfortably dangle you are going to come unstuck, or indeed if you are going to come then you will have to finish yourself as your partner(s) may now be suffering a slipped disc.
Rule 34 aside see how teledildonics is a thing, VR is a thing, fine grain searches are a thing, streaming is a thing and nobody is in a particular hurry to create smellovision here. Barring anal, itself a minefield, the smells involved should not make you wretch but they are only going to remain a somewhat specialist line of perfume.
Part 4, the parting of the (beef) curtains. If you have been trained in the post 1970s world* you may have something of a pathological aversion to body and pubic hair. The merits of this can be left for discussion another day (though as it is an advertising induced state of affairs I am inclined to question it heavily). The end result of hair removal is not always fun though - spots, discomfort, ingrown hairs, laser/electrical burns... porn can hide this with either CGI (expensive and it is not the most lucrative industry any more with the competition available) and makeup (if you have ever had such things wafted into your face it is not pleasant, if your face is down there then it is also not pleasant). While the aversion to hair may hold little rational position the aversion to damaged skin is deep rooted in biology (indeed it is speculated that backless dresses are so alluring to some as it showcases extensive undamaged skin), though in this case it is one of those biological drives which can be ignored to an extent and if attempting to be an upstanding member of society one... soldiers on, maintains a stiff upper lip (though that is a more advanced technique), or lies back and thinks of England. Also for discussion another day is whether a bird using the hand is indeed worth more than your two in a bush.
*much like Japanese catnip their approach to the delights of the pussy may differ here, sadly while hair is still present and available if you go looking the supply of pixelated sexual organs probably died with dial up. Additional options could include getting so inebriated it is all a blur but that is a path fraught with peril, to say nothing of possibly then forgetting it all and if it takes that much effort you surely want to remember it.
The advantage of porn is that you don't have to deal with real people.
