Few things

1) All the senses. Sight of a physically attractive man, smell of his sweat and musk, the taste of his skin and sweat, the sound of the plapping and his grunts and moans and, if he is a good dirty talker and knows what to say to turn you on, all that

2) Automation. Having someone fuck you means you spend less time engaging your muscles, which means your neural pathways are less engaged and distracted

3) If he's a good top, he will listen and learn and interpret your needs to speed up, slow down, go harder or softer, change angle and position. I really good top will fuck you and make you orgasm even if he doesn't cum, or keep going if he does
