am Kim, have black hair, 2m high. I have been masturbating for the last 10 years since i do not have a wife and life has been going on well, am currently 31 years of age. But these days when i masturbate i take too little time two minutes only to ejaculate and when i also go for sex i last for a short while something like three to four minutes only. so what can i do to increase on the amount of time i take when having sex. Cause it looks like i do not satisfy the girls in bed which leaves a question mark, i really need your help doc
