Chapter 1

Silas considered himself to be a normal guy. He was straight and cis, wasn't into anything that kinky and while he wasn't some kind of stud, he did have a couple girlfriends and had a few one night stands. Right now he was dating a girl named Catherine and he was having a good time. She was a stunning blonde with big tits and great curves. Honestly, he didn't know how the fuck he got her.  She just walked up to him one night at a club and before he knew it they were fucking and shortly after dating. 

Silas had no complaints. She was a very feminine girl but surprisingly low maintainince. She was smarter then she looked (she definitely gave off that "bimbo" look) and was actually kinda cool. Plus she was fucking killer in the sack and she wanted to have sex often. Honestly some nights he couldn't keep up.

And that was part of the problem because the more he dated this girl, the more exhausted he was becoming. Weird as it was he found himself having strange dreams...nightmares really, after he fucked her. Weird fucked up shit. Spiders laying eggs down his throat then their young eating their way out of him. Getting fucking pierced with spears and tridents.  Being covered in ooze that slowly digested him. He could go on and on but they were fucking awfully and not conducive to a good state of mind. 

Another thing was...he just felt worn out after fucking her. More then he should even after a hard fucking and a shitty night of sleep. Like barely able to get through the day, nodding off at work tired.  He survived off energy drinks and while this may be normal, a symptom Silas supposed of being on the brink of graduating his twenties, this sense of exhaustion would carry on for days after each fuck. Enough that it was becoming impossible for Silas to see her now except on weekends.

Thirdly, the pain. Yeah the day after sex with her, he hurt. Not like STDs. Catherine had actually voluntarily got both of them checked for that early on, but a deeper pain. Pain in his bones, pain in his heart. Awful fucking headaches. It took a lot of forms but it was bad and persisted and got stronger as time went on. At first it had barely been noticeable, now between exhaustion and the pain it was near impossible to get himself out of bed. Good fucking thing he worked a desk job. 

The doctors thought he was fucking crazy, cause they couldn't find shit wrong with him. Catherine herself seemed right as fucking rain. So it wasn't a spreadable thing. And with the way things worked out, he felt better by the middle of the week and good as new when Saturday rolled around. 

So at this point the question remains, why the fuck didn't he just stop seeing her. That was for three reasons. 1: The sex was that fucking amazing. Best he had by a fair distance. 2: He thought that if he broke up with her for these fucking bizarre fantastical reasons he just might break completely. 3: He really fucking liked her. As unexpected as it was he might be falling for her. 

But he couldn't take this much suffering. So the sex was reduced from just Saturday and Sunday, to just Saturday, to Just Saturday every 2 weeks.  He couldn't believe that he was openly choosing to have sex with his girlfriend this infrequently, but he had to. He found in time that his sex drive was also decresing. For some reason, maybe conditioning, he no longer felt the need to have sex more then once every two weeks.

At some point, he found even this too much. He began to dread that saturday. Fear it and how it would make him feel. The terrible dreams, the exhaustion, the pain. None of which diminished. Finally, as Silas was watching Catherine disrobe, he had had enough.

"S-Sorry. I can't tonight." Silas said.

"You don't want to make love tonight?" Catherine asked.

"N-No. I don't. I'm sorry." SIlas said.

"No. No. That's ok. You never have to do something you don't want to do. Don't feel pressured for me. Let's watch tv and relax." Catherine said.

Never had Silas felt more comforted in his life. However a new fear was building within him. No longer did the sight of his hot girlfriend inspire an erection in him. Now it inspired merely dread. That wasn't right. 

What the hell was happening to him? 

For a time Silas had been augmenting his single bi-weekly fuck with masturbation. However after a couple of months that diminished to nothing. The day after he denied even that sole sexual encounter he tried masturbating again. To his horror it didn't much work. Looking at naked women elicted that same sense of discomfort and dread seeing his girlfriend disrobing now did, and he tried to masturbate despite this, it made him feel that same pain.

He retreated from his attempt pretty quickly. After that he stayed away from porn for a week. He tried again, however, the lesbian porn that was his standard now not only induced that dread but also disgust. How had he ever liked this stuff in the first place? It was sick. Wrong. Not for him.

Those thoughts terrified him even more. For a month he tried his hardest not to think about it, but it was only a matter of time before the issue reared it's head.

He was watching tv with his girlfriend when he felt the first strains of sexual arousal he had felt for a while. When a man took off his shirt, revealing his bulging muscles. His cock finally found something it liked. And it was this attractive shirtless man. 

He thought he would have panicked. But surprisingly he didn't. This situation felt dreamlike but also very, very hot. He wanted the man to take off his jeans next and then his underwear, leaving his entire body exposed. The male body had such beauty to it. He had seen that. Hadn't he been starting to feel that? When he was out in public and saw an attractive man? Something was awakening in him, he was certain of it. And right then it didn't feel scary. 

He went to bed beside his girlfriend, but she was the furtherst thing from his mind.
