How can I postpone my s?

I want to know how to help me last longer in bed! I masturbate maybe 3 times a week at most and I wonder if masturbating dry (without lube) or using lubricant would help me better. I figure since penile surgery is a total mistake and pills and pumps don't work, I'm gonna make the best of what I have, which is average. I know there's kegels but don't really know how I'm supposed to do those so, is there any way to maybe get my used to a long jerk it session while lubricated? THX!
