There is no reason to be ashamed about ejaculating too soon, it happens to almost every man and it's unfortunate that stars of adult movies have lead most men to believe this is how long they should last. Little do you know that these scenes are repeated over many hours as the erection comes and goes.
The reality is that men orgasm too quickly because the sensation is too strong. The solution to this is to use a topical delay cream which is a safe anesthetic to slightly numb the penis which helps you to last longer because the sensation is not so strong.
