What can i do to lazy longer during sex?

A few ideas: I'm going to assume that you are asking about premature ejaculation. Using a condom or a bit of anesthetic on the glans may slow things down. Your physician may be able to offer you a very low dose of a selective serotonin reuptake inhibitor; this helps. Best is the squeeze technique, in which you and your partner learn skills that will bring a lot of mutual enjoyment.
