I am very much impressed by your site and found it very helpful. I used your tanner stage calculator and got 4.5. I have a concern: while masturbating it takes me 3-5 minutes to ejaculate. I have heard adult men last for 30 minutes to an hour max. I am worried if my time will be the same forever or if will increase as I grow. I don't want to ejaculate so early. How could I increase my stamina for sex for my future wife?
Thanks in advance.
Claims and reality are two different things. When people are having intercourse, time isn't tracked well. What seems like a half-hour can really be only five minutes. Then there is the problem of what is being measured. Are they counting from the first touch or from when the penis first enters the vagina? Most studies that I've seen says that the median length of time for actual intercourse (when the penis is in the vagina) is 5.4 minutes according to The Journal of Sexual Medicine [WebMD].
