Well, I've only blown two guys, so my experience isn't very excessive, but in my case that's false.
You see, my highschool sweetheart was pretty average on the cock department (he once measured it, and yep, average) and I had no problems taking his whole cock inside my mouth, but he never seemed to be able to enjoy the blowjobs that I gave him. I'm not sure if I was simply so bad at it, but
he said that his cockhead simply wasn't sensitive, and getting blown didn't feel like anything. Once I sucked him for well over an hour, and he still didn't come. (You can just imagine what this did to my self-esteem! :tongue
Anyway, we split later on, and I started seeing this new guy, who later became my husband. Now, he's BIG compared to my ex. A lot thicker, and an inch or two longer. Pretty much the yummiest cock you can imagine. :tongue: He loves it when I suck him, and I love sucking him, not just because he tastes and feels so good, but also because I know that I'm bringing him pleasure. I don't know if I'm giving him better BJ's than I gave to my ex, but my husband seems to enjoy them a great deal more, and I've never had any difficulties in making him come.
So, in short, the smaller guy didn't enjoy the BJ's, while the bigger guy did.
