How else can you keep yourself from coming with out masturbating prior to?

There are several methods I have experienced and read or heard about.
1. numbing the male genitals. This can be done though the use of ointments, ice, alcohol, psychological tricks or repeated slapping.

Many men will slow down there arousal by slapping there tool against a tongue, clitoris or anything else. This absolutely works. It not only slows down your progress but in some cases actually stimulates her from the change of pace. Additionally, it can spice things up and add some fun.

Chemical numbing works but can have negative side effects. Ointments and oils can burn or be uncomfortable for her. And alcohol can be damaging to the liver and if you don't watch your limits closely can lead to an embarrassing inability to perform or complete the job.

The simple use of ice can be fun an exciting . She will enjoy icing her mouth before giving oral but rarely do females enjoy ice downstairs. They may be willing to try it which will be fun. But I have seen second trips are tougher to make happen.

Psychological trickery works well (like imagining your grandmother to slow things down) but you may come off as distant or not in the moment.

The best results are from having sex regularly, perhaps once a day, eventually the male production levels will be met and his urgency to orgasm will slow. Try having sex the night before for him and in the morning he will be likely able to last for a good 30 -45 minutes of raw fun with no tricks needed.

Ultimately use any tools available (hands, vibrators, tongues, etc) to help her orgasm and she will come back for more. Leave her high and dry and she WILL go looking for satisfaction somewhere else.

Stamina is important, but style, effort, and connection makes the real difference. period.
