So I was the typical teenage skateboard weirdo, back before skateboarders were the hot thing, haha. Hence, I didn't really get a ton of girls until high school. A consequence of this (which I am certain many men on this site will relate to, based on the presumption that many of us were probably not the most popular kids in school), was spending many nights furiously jerking off to porn, usually featuring an extremely large man pounding a desensitized pussy. As a result, I was very unsatisfied with my own package, believing that the average cock was a porno-dick. It wasn't until later in my teenage life, when I started having sex on the reg and getting good at it that I realized I was actually very well hung. 7.5" erect, quite thick, straight, nothing off about it. The nutsack is pretty normal, nothing out of the ordinary; it hangs with the best of them. I just always thought that was the average. But every girl I had sex with had trouble taking it for the first few minutes. I stood-or more appropriately, hung-corrected.
However, don't take this as me just gloating about my amazing penis. It takes a smooth, gentle technique with the vast majority of women to have a thicker, fairly long cock. A good few girls I've dated have been virgins, which is just difficult to work around with a large member. And even months after our first experiences, I still had to go very slow for the first five minutes or so. My partner and I have been having sex for a year now, very often, and I would hurt her badly if I just rammed it in there. The proper technique seems to be more of an exploratory poke, followed with a couple expletive-laden moments before the jackhammer can rev up.
The denouement here, is that having a big, thick cock can be great. You can work out some really exotic positions. You'll be able to rub against the vaginal walls more easily, which the majority of the ladies of bluelight will certainly admit is real proper fucking technique. You can cause more contact with those vaginal walls, and the g-spot in positions which would otherwise be in-out, low friction affairs.
However, there are just as many downsides. Insertion is an intricate motion; done too fast or too dry, sex will violently end before it begins. It takes a little bit to acclimatize the vagina to its new friend, so taking it slow at first might flaccidize an insensitive cock. If you go for too long, and things start to dry up, rubbing the wrong way could pull the skin inside the vagina, causing agony and/or bleeding. Worst case, pray it not, the tragic event of a slip-out anal poke could occur, and being a large man thrusting con gusto into an unprepared asshole will bring a crashing halt to any sexual conduct for at least a few days, provided that your partner doesn't turn you down, fearing a repeat reaming.
My genitals and I have had a complex relationship, but I've concluded that most men have a fairly unrealistic perception of their cock, and an even more unrealistic perception of what women want their cock to be. Most girls have no desire to be turned inside out by a mandingo dong. Even a below-average cock can garner praise with excellent technique. Yet with improper maneuvering, a perfect specimen will just tear a new hole in your partner and your sex life. The happiest medium seems to lie in a comfort zone a little above or below average, but size is nothing without technique. In fact, I venture to say in all but unreasonable circumstances (no baby dicks or kong dongs), technique is 40% of good sex. Attraction makes up the other 40%, and size is a meager 20%. An attractive guy that can handle a woman like eros can usually make up for being kinda small or large. So unless you have a serious issue, don't fucking worry about your dick. Work out, eat right, dress well, work on your game, do something with your life, and learn how to fuck. If pleasing women, for you, is a problem, your cock is usually the smallest part.
