If you men ever wondered what constituted 'premature' ejaculation...well, the linked article defines it for you.
If you...ahem...finish in under 2 minutes, you're a premature ejaculator.
Make it to seven minutes and consider yourself able to stay the course.
Which leads me to wonder what the dudes who fall into the five minutes between 'premature' and 'staying power' are classed as.
Got any ideas?
