Ever noticed sometimes when you try to have sex you just can't get hard or can't stay hard? It could be your mojo. Mojo is like libido - your sex drive. It's affected mostly by when and how often you orgasm. Mojo builds up slowly over time. It gets depleted at orgasm. The more you orgasm, the lower your mojo will be in general. If you have 3 orgasms every day for a week, by the end of the week your mojo will be very low. If you then try to have sex, you'll find it difficult to get and keep an erection.
If on the other hand you haven't had an orgasm for the last 3 days, your mojo will be high and you'll have no problem getting hard. It doesn't matter whether you have the orgasms through sex or masturbation.

Your body actually takes note of your mojo and makes decisions for you, possibly without you noticing. For instance, if you know your going to be meeting your girlfriend tonight, you're unlikely to masturbate past orgasm an hour before you meet her. Your body might be doing this unconsciously for you...

Big Mojo = Big Orgasm

The higher your mojo, the more intense an orgasm will be for you. If you came twice yesterday and twice today already, another orgasm now (if you can manage it) will be pleasant, but nothing to write home about. If you haven't come for 3 or 4 days, today's orgasm will be spectacular. With your high mojo there will also be more semen and it will shoot out further. mmm mMm mmm.

If your mojo is high and you have sex and orgasm, you'll find you'll be able get an erection again and be ready for more action quite soon afterwards (within 10 mins or so). If your mojo is low and you have sex and orgasm, you'll probly find you just want to sleep and you'll stay soft.

Can I come too much?

No. It's impossible. If you orgasm a lot over a short period, your body will regulate your mojo. You won't be able to get an erection and thus won't be able to reach orgasm again. Until your mojo builds back up again.

Can I come not often enough?

Yes, this is possible. Especially if you are older. Orgasm and ejaculation are controlled by the prostate muscle. Like any muscle, it needs to be exercised. If you go for a long time without orgasm, say four weeks or more, the health of your prostate may be suffering. To remedy this, just masturbate. If you have trouble or experience any pain with orgasm, sex, ejaculation or urination you must go and see your doctor. Don't leave it; do it now.

No Sex before the Hunt

Mojo is why some sports coaches swear by making sure their players don't have sex before an important game. This phenomenom has also been noted in some hunting cultures where people religiously avoid sex before the hunt. But it's not really about sex; it's about orgasm. If you haven't orgasmed for 3 days, your mojo will be high, along with your general drive and aggression. If you have an orgasm 30 minutes before a game, you'll be satisfied, but drowsy, with low drive and low mojo.
