I feel like it's strange for me to answer this question since I am 14 years old but...it's completely normal for a lot of semen to come out, but the more frequently you ejaculate, the less it is. If you feel like you are going to come too soon, then take a 30 second pause. Hope this helps!
Meditation is a practice in which, it seeks to have an adequate mental balance that allows to block all negative external interference, is not necessarily done with sounds.
