Dr. Sawyer: Most young men get an erection in two to five seconds (yes, they’re pathetically easy) and could probably ejaculate within a minute or so. The key to preventing this is communication. The guy needs to be able to tell the girl what’s going on, how close he is and to maybe slow down. Men, don’t buy into an urban legend like thinking about baseball or your grandmother! That’s the worst thing you can do. Be bold and talk to your partner, you might be surprised how effective this can be.
