色情自我按摩

For the next exercise, your penis should be erect.

Using both hands alternately, make loose fists and run them very gently downwards across the penis from tip to base.

PC muscle training will help you control the erection and give you more endurance while having sex.

You can learn how, by contracting this muscle, you can postpone orgasm and ejaculation and even prevent seminal discharge.
