Maybe I have a problem because to me anyways it is nothing special. IO mean it is not unenjoyable, but I don't get that deep into it. As far as my description - they are all different. How hard/soft, how big, the taste, the smell. When guys are soft sometimes it i like you are just sucking skin, when they are really hard sometimes it is like trying to stick a too big sausage in your mouth. It can get exhausting sometimes, and you wish they would hurry up and just cum already. Your jaw will ache afterwards. Then again, every guy tastes different.
Personally, I prefer thinner, longer cocks. I also love sucking on balls, though many guys aren't into that.
Emotionally, I actually find it a little detached, as unless you are in the right position, you are really just looking at an extreme closeup of his lower stomach. Then again, when you do connect, especially eye contact and you can feel his enjoyment, it is quite ecstatic.
