Hey, i'm a 19y/o virgin who mastarbates once a week. i only last for like 2-3 minutes when i do it. will this be the same duration when i'm with a women? is there any way i can increase my lasting time?

Climaxing quickly when masturbating is largely a learned behavior and can be relearned to last longer. When beginning to stimulate yourself, pay attention to the sensation building up & getting close to a climax. Flex the same muscles you use to stop urine while squeezing the area behind the head of the penis. As the erection subsides, re-stimulate yourself to a full erection, repeat to climax.
