How can Big Guys have such Small Cocks?

OK, so I got together with a guy from the gym. Stupid? Maybe... Jury is still out. He's married and looking for a friend with benefits. Says his wife has no interest in sex, and he caught her out with a guy once, who she lied about. I'm his first cheat, so I set the bar I guess. Now I am about to swear off men in general because they are so annoying. He's a power lifter and 280 or something - so I had a 280 pound bundle of nerves, and a worrier. So we met at my house and of course (cue ironic music) it is near his wife's sister's house. He is kissing me and licking me, and has already said he's never had furry pussy, so he's trying to lick it. Well he may never have it again. I was pretty turned off by his half grown in stubble from shaving his whole body. Then I went down on him, and what do you know - could barely find it. He had sent me cock pics on the phone which made it look average size, then he said several times he did not have a porn star cock, just an average one. Well let me tell you, it is not average. It is smaller than average, by quite a bit. I wonder who he compared that to, to call it average. Also, barely any balls. Weird, just a little widening of the shaft and I can barely feel any balls rolling! Sex-pervert fiance says it's from steroids, but he may just be jealous of the 280 pounds of muscle. It certainly does look like he would have a dick on him, but no - I get all the way to bed and I can't even feel it. Fiance was pissed at my careless cuckholding, which failed to show him any good camera angles. He pouted, called me in the middle and has put me off showing him sex with other guys ever again. Powerlifter was so nervous he had trouble getting hard, and frankly it's a good thing I did not expect a condom (he's tested safe and vasectomy-city) because I don't know if they make condoms that small, and it's seriously hard to get hard for a condom when you are so nervous. He thought he could go several times, he did cum twice, but was not very hard. Made a big deal about not eating me again after he came (big deal, you expect me to swallow it) and then he was so very nervous it made me pity him, not crave him. I forgive him the nerves and he was really sweet but I can't put up with all that for such a tiny dick. There, I said it. I have limited time, limited patience and apparently more criteria for girth than he can fulfill. I'm blaming it on fiance sex pervert, and saying he did not like me having sex and ignoring him. That's part of it, but the whole story is pretty crushing and would do no one any good out loud. I do think his wife has interest in sex, just not sex with him. And I can unfortunately see why. Also I think I'm allergic to his cum, which made me itch a little bit. BLAHHHHH Fuck men. I think I'll actually swear off fucking them.
