Advice from a retired expert (me) about masturbation

If you are watching a long porn clip, many people face a problem, which is that they cannot wait until the porn clip is complete, as they reach orgasm suddenly and unwantedly.

The solution is to masturbate until you get the feeling of goosebumps, which comes right before semen is emitted, then stop and wait approximately 60 seconds (according to international time), and then slowly repeat masturbation again.

The wonderful part is that it may last for an hour, with an average level of euphoria, and when the relief you will feel is literally indescribable.
