I pump between 5 and 10 for two or three 15-minute sessions, 10 min. apart. I start at 5 and usually stay at about 7, going up to 10 for about a minute, then back down to 7. Every 5 min., I drop to about 3 or 4 and jelq the tube. I find this quite comfortable (but I’ve been pumping for almost four months). I head straight to a hot shower in between sessions, then jelq before the next session.
