I am not sure if it is because I have a very large penis that most women cannot handle, but I am surprised at how different each girl feels. I remember a few girls in the past usually the sex feels kinda numb, like you know if someone rubbed your arm you can feel the sensation but it doesn't really do anything for ya. However some girls it feels so soft like a massage and you cannot help but explode right away.

Most girls I can go a long time since the feeling is hardly anything while some their vagina feels really hot (like a hot temperature) and soft and wet and it feels so freakin good. Whereas other girls it feels like hardly anything even if they do not have sex a lot.
