I am worried about my sex life because i release quickly like in seconds. my partner is never happy. what can i do ? is there any treatment for this ?

Let's fix you: A condom and a dab of anesthetic on your glans for starters. Ask your physician whether a tiny dose of a selective serotonin reuptake inhibitor is in order (it works). Best of all, learn the squeeze technique and work with your partner on ways to bring each other pleasure beyond what you may have imagined possible. Your physician may be able to help. Good luck.
