Masturbation is sexual stimulation designed to produce an orgasm through any means except sexual intercourse. The term evolves from the Latin word masturbari, which means "to pollute oneself." All through history people have been made to feel guilty for masturbating, but masturbation is natural and fun. Masturbation does no inhibit enjoyment of sex with a partner unless the masturbator becomes obsessed and does it continuously or in public. More than 97 percent of guys admit to masturbating.
There is no normal amount of times to masturbate. The only problem you might have from masturbating constantly is a sore penis. Many males discover masturbation by accident, when one day they're rubbing their penis and it feels so good they don't stop until they have an orgasm. But a good masturbation session can go a long way, and there are many ways to make it more enjoyable. Like sex with a partner, it's much more enjoyable when you can relax and take your time. You can masturbate privately or if it's mutual, you and your partner can go about it in your room.
Most men focus on the head of their penis since the majority of the nerves are packed in that area. The scrotal sac and testes are not as exciting for men as stimulation of the labial area or the vaginal entrance is for women. A man concentrates his efforts on the glans and frenulum. The shaft is rather insensitive, but allows him to move his hand up and down rhythmically.
How to do it?
If you already do it and enjoy what you do, chances are you know how to masturbate. If you're looking for other ways that bring you more pleasure or even if you just want to experiment, then read on.
Some guys masturbate by rubbing their penis against their mattress. Some men do it by inserting their penises into specially made rubber dolls and devices that look and simulate a vagina. A lot of the devices require lubrication to make the rubber feel more real. For those who cannot afford to by such device (some range between $30 to well over $100), there are other common techniques that only require common household lubricants.
Some guys put Vaseline, lotion, or baby oil in their hand or on the shaft of their penis. While some chose to masturbate lying down or standing up, others could care less what position they are in. For a guy using a lying down technique, when he ejaculates, the semen will end up onto your chest or stomach, so it will be easy to clean up (you would need to have Kleenex or paper towel on hand). For someone in the shower, cleanup is a much easier task and you can just wash it away and there's also a lot less chance of someone walking into the room.
As with everything in life, practice makes perfect. Once you find a technique you like, show your partner and you can use it during mutual masturbation.
