Jack or Jerk

Since it usually sounds like some kind of a dirty Dr. Seuss book if either of those are used in conjunction with my name (Jack), I use "stroke". It sounds less ridiculous to me. :)
 
"I ejaculated a huge load when I masturbated, last night!"
"Last night, I wanked out quite a gusher of spunk! Jolly good times!"
"Dude, I jerked out a huge fuckin' load last night! There was so much pre gushing out the whole time."
"I was jackin' so long last night that the bed was soaked in pre. Had a huge cumshot at the end."

Hmm... I think it's context. XD
