I pleasure myself, but I couldn't ejaculate next day, how long do I have to wait?

Hi Kid When you first start to ejaculate it is common to not ejaculate every time you masturbate. The orgasm without ejaculating is just a dry orgasm and having one or trying daily won’t hurt your penis in anyway. It just means you have reached the point in your development that you are able to ejaculate but it won’t necessarily happen every time you can still experience all the pleasure associated with doing it there is just no need for the clean up afterwards. So trying won’t harm you in anyway and waiting a few days won’t guarantee that you ejaculate so it is just down to what you feel is best for you.
