Do not overdo masturbation

Do not overdo masturbation girls. Because the area down there is so sensitive, after you orgasm it takes a while to rebuild your sensitivity. If you are constantly pleasing yourself, your partner is going to have a hard-ass time trying to get you off. Also, try to avoid using vigorous vibrator or massagers of any kind. Your girl or guy can't match the force from an electronic device, so keep them in mind. Bottomline, if you enjoy pleasing your partner and being pleased by your partner, save the love for them. Besides, you are going to get a better orgasm from your partner anyways, if you give them a chance.

Using a vibrator

A vibrator is one of the most popular ways in which a woman can achieve a novel sort of orgasm – either by using it on herself or with her partner working it for her. The main purpose is to use it on the clitoris and, by increasing the speed, to bring the woman to orgasm as powerfully as possible. But a vibrator can lend itself to more creative use. You merely have to instruct your partner how you want it done.

You can lie down on the bed facing upwards or, alternatively, face downwards on the bed and place a couple of pillows under your stomach, as in a conventional rear-entry position.

Better orgasms with masturbation

You can experience deeper, more intense orgasms by making one little change to your masturbation routine—breathe deeply. Most of us hold our breath during sexual arousal, waiting all tensed up for that moment when the climax washes over us. But take long, deep breaths while you're masturbating and you'll notice that you can feel the sexual energy flowing throughout your body. You'll probably also notice that you can time your breathing with your mounting arousal, which can help push you along toward the orgasm. And you will feel the orgasm down to your tiptoes when it does come.

Routine is bad

The trouble is that many couples do get locked into a fairly predictable approach to their own sexuality and that of their partner. A rigid routine, in terms of time and place, followed by a predictable approach during every lovemaking episode can tire anyone's desire for sex.

Many couples could – if they were so inclined – put a stopwatch on their love-making and find that intercourse took place at the same time of the week and in the same place, and that its duration varied by no more than a few seconds each time.

Why do orgasms vary? (part 2)

Please read "Why do orgasms vary? (part 1)" first.

A woman's sex drive varies much more subtly – both from woman to woman, as well as during each individual's own menstrual cycle. Add to that a generally more emotional approach to sex, where orgasm is part of a more complete experience, and it becomes considerably more difficult to pin down a woman's frustrations and sexual needs.

Nonetheless, there will be periods in her life, in the same way as there is for a man, when her own orgasm is so powerful, so memorable, that she just longs to be able to repeat it frequently.

The most advanced lovemaking techniques can leave both sexes cold if the mood is wrong, but in a loving relationship the ability of a man to sustain and control his erection or the woman's ability to control and pace herself can make a great deal of difference to the quality of not just their own, but their partner's orgasm as well.

Why do orgasms vary? (part 1)

We’ll experience many thousands of orgasms in a lifetime. Yet, later, if we looked back on our love lives, most of us would probably remember just a handful of episodes when our own orgasm was truly memorable. The rest might have been quite satisfactory, but some lovemaking episodes have a quality that sets them apart. Often, there appears to be no reason – and it was probably more than the sex that made a particular memory linger on.

For a man, there are biological reasons as well as emotional ones which explain these kinds of variation. Although the male sex organs are consistently efficient at creating seminal fluid – some younger men can have orgasms many times in a session – if a man has not had sex for some time, the release of semen can be extraordinarily powerful. It is not just sexual frustration but a physiological need – a desire for sexual release.
