Sexual Relationships 
Sexual Health 
I enjoy porn and sometimes read erotic stories online, because I love fantasy. To me, all sex is fantasy. Even successful relationships are usually built on an imagined idea of an ideal lover.
The best part of fantasy is sexual tension — that feeling of anticipation just before it happens for the first time. For a woman, it might be that feeling where her crush walks in while she is alone in the room, perhaps wearing something revealing and unusually scant. She wasn't expecting him. He sees her, starts, looks her over, then smiles. He approaches. His intentions are unclear. She has dreampt of him, masturbated to him, and now...
Or perhaps she is at a formal occasion, dressed to the nines, looking gorgeous, and she knows it. It is a lovely summer evening. She strolls out on the grounds and sees her crush in the distance. Perhaps he is lighting a cigarette, or taking in the fresh air and cool breeze. She wants to know what he doing out there, and tries to observe without getting caught. As she edges closer, it is to no avail; he sees her. He looks her up and down, throws his cigarette to the ground and smiles. He approaches.
For a man, it might be that moment when his crush appears as expected, but she looks more excited to see you and more beautiful than anticipated. Or when, after days of noticing and longing for her from afar, she knocks on his door. When she is sitting close and then touches his arm, unexpectedly. When your crush sees you in your dorm exiting the shower, wearing nothing but a towel, and she pauses to take a second look. Or perhaps even when you approach a woman, and she unconsciously takes a good long look squarely at your crotch.
I'll bet you can come up with more, perhaps better examples. I hope you do.
These are the most exciting moments of the narrative of sex - the unknown, the anticipated, the longing, the unintended (or subtly intended) teasing. The possibility of more, looming before you, like a delicious fruit waiting to be plucked, bitten and consumed. The precipice of everything.
The second best part of fantasy is ecstasy: the glazed look in their eyes, where they are so engaged in the sexual act that they lose themselves. They look like they are stoned; high on the sexual act. They are surfing on their own sexual excitement, like a wave that has scooped them out and carries them out another place, another state of mind apart from this mundane world. When I am in ecstacy, I feel as though I am dwelling in my own dream.
The rest of porn and sex stories is more or less the same. Without tension and ecstacy, every fuck looks the same, and it is as boring as, well, boring as fuck.
