Hello..is there a way i can improve my sexual intercourse duration last longer? this is quite embarrassing

YES- squeeze method: sensate focusing: takes about 4 weeks: Week 1- touching/kissing with clothing on. Week 2- touching/kissing and prolonged foreplay ( 10-15 minutes)..have partner use "squeeze technique, using a firm squeeze to the head of your penis if you think you are going to ejaculate-squeezing until sensation goes away Week 3- pronged edging foreplay just to the point of coming and squeeze Week 4- intercourse

Cricket?: If this is a big issue you may consider a pre round solo prior to your encounter. A bit drastic but you will go longer a second time. Think about something else not sex that may help also.
