What can help one last longer when having sex?

For a man...: I recommend the old "squeeze technique" == when he feels ejaculation is inevitable, have her squeeze him until it stops. He eventually learns to slow himself down. An easier manever is a very low dose of a selective serotonin update inhibitor if his physician thinks it's save -- this delays ejaculation in almost all men. Remember that premature ejaculation isn't a sign he doesn't love you.
