When Spider-Man rubs his wrist using his hand until a white sticky substance is released, often called, "His Webbing". Spidey often uses this "Webbing" as a form of transportation among other things in order to save the day. This is why when Spider-Man isn't horny, the day does not get saved.
Person - "Help, I'm being robbed!"

Spider-Man - "*Frantically rubs his wrist and moans* Come on you son of a bitch!"

Person - "Is he jacking off?"

When a guy slides his hand up and down slowly or really fast, however he likes it, on his hard dick until he gets that immense feeling. That feeling is one of the most desired feelings in the whole world and when it happens, you get ready to shoot your warm load all over the place.
O man. I was jacking off last night using this lubricant. It felt so good when i shot my load all over the place.

Jacking off is after you play withself and can't hold back the pleasure and excitement you just created playing with your self, then you cum.
I love to play with myself while looking at pics of girls on the internet. I can do this for hours and really love it. I like to put rubber bands around my balls, they make them bounce around alot while jacking and feeels real good to me. I like girls to watch me play with myself also , mostly they just laugh, especially when I can't hold back any more and finish playing by jacking off. Watching me cum, they laugh alot , I love it.
