In a nutshell, here's what desensitizing condoms are: They are typical condoms except for one major difference: they contain a numbing gel or ointment inside the tip of the condom.
When placed on, you will feel the gel on the head of your penis.
What will happen within the next few minutes is that a "numbing" like effect will take place.
You penis will essentially become highly desensitized.
Alright let's get straight to the good, bad, and ugly regarding desensitizing condoms for lasting longer during sex.
The Good: Well, truth be told, they can have you lasting much longer than usual.
Since the penis is not as sensitive, you won't feel the usual "over-excitement" which can occur very early during sex.
Because of this, you will be able to hold out much longer.
The Bad: You potentially won't feel much during sex.
There's a major downside to desensitizing condoms and that is while you could last longer, the tradeoff will be that you won't feel much during sex and the overall sexual experience will be downgraded significantly.
The Ugly: The ugly can happen rather easily.
Everyone fumbles around with condoms as we try to get those suckers on as quickly as possible.
With the desensitizing kind, imagine being caught up in the heat of the moment and putting on the condom the wrong way (inside out).
Guess who's going to be receiving the "numbing effect"? Not you.
This can obviously be a huge backfire, a major FAIL.
Best Alternatives: Even if you are using these condoms, you still should be working at trying to last longer during sex naturally, without having to rely on creams or special condoms in the long run.
You can learn to last naturally through exercises which will basically train your body to hold out and not ejaculate quickly.
These work extremely well, and best of all you get to enjoy sex to the fullest, instead of being all numbed up throughout the experience.
