I can tell you, from experience.. the orgasm is SO rich, so heavy, guys who don't see precum, will I assure you. You will clinch muscles deep in you body until, after 10 minutes you have ropey festoons of precum, and then when you kick the energy level up a little more, nothing on god's green earth could stop what is cumming. like a moon rocket, hitting the ceiling. If want to hear more text me.
