As discussed previously, the average time for a guy to last in bed is 5-6 minutes. But if you are a man who last this or less you may well be looking for an edge.
So here we go!
Need I say anymore on this one. If you can at the start, focus primarily on your partner. According to studies, less that 25% of women orgasm during actual intercourse, so to give the appearance of lasting longer and to ensure your partner is fully satisfied, foreplay is imperative. As a general rule of thumb, you cannot do enough foreplay.
Another option is during masturbation (which I am assuming every guy does) is to keep going as close to the PONR as possible. The PONR is the Point Of No Return. During masturbation if you practice going as close to this point as possible regularly, you will gain control over the feeling and be able to better control your orgasms during sex.
As a rule of thumb it is good to practice during masturbation of going as close to the PONR about 10 times, stopping and repeating. This process is known as Edging if you want to search for more information around it. The theory goes that it is better not to orgasm as the end of it, if you are looking to gain extra control, however, I have found that it works well either way.
Pelvic Floor Muscles;
Using a thick condom will reduce sensitivity and may help you last longer. As well it doesn't stand out as being a cover so suitable even if you are with a stranger.
Masturbating before sex;
This is one that you probably need to experiment with. It will either work for you or not. A lot of people swear by masturbating an hour or two before sex. This will help reduce sensitivity also. Again it works for some not for others so try it out if you want.
