I hear ya, man. I am a male in my late 20's and I do this myself. From my experiences, I can conclude that both men and women can make themselves cum quickly through masturbation...well most of us anyways.
Each person knows what feels good to them and knows how they want their typical sexual acts to play out. As an example, I have been sexually active with several women over the years and each one was different in how they like to be touched and fondled, etc. I am not saying that I am a mac-daddy or player or anything. I am just trying to speak from experience.
If you are worried about climaxing too quickly during intercourse then there are a few methods that you can practice to prolong your erection and satisfy the lady as well. For one, masturbate slowly and do not think about having an orgasm while you are masturbating. Try to keep that thought out of your head, though I understand that it is rather difficult.
When you finally feel that you are about to cum then stop everything. Do this several times during the course of your masturbation. Eventually you will find that you can control it. It does take practice so do not be discouraged if you climax when you do not mean to.
Another trick that I tought myself was to masturbate until the point to where I was teetering right on the edge of orgasm...the point to where one more touch would do me in. At this point, I learned to pinch down hard on the urethra, right where the shaft of your penis meets the scrotum. Pinch it off just like you were stopping yourself from urinating. Trust me...it works and I have even done this during intercourse with a woman. Stopping intercourse right in the middle of the act sucks for both the man and the woman, but in the end both people are thankful. It is better to cum later.
Also, when masturbating and having sex breathe deeply and not in quick pulses when you practice these methods. The orgasm is mostly located in the brain and not the genitals. By giving yourself more oxygen and concentrating your breathing it will be easier to control yourself from cumming.
By the way, I am no medical expert or sex therapist. As I previously stated, this is from my own experiences.
I hope that it all works out for you, man. I practiced these methods myself and within a few months it was pure instinct to know when I was going to orgasm and I was able to prolong both sex and masturbation for very extended periods of time.
I hope this helps.
if i try really hard to make myself cum jerkin off, i can cum in like 3 minutes too. when i have sex tho, even if i try really hard, it still takes about 10 minutes. What i usually do is fuck at a good but not all out pace to make my gf cum then i fuck like crazy to make myself cum.
Well, I could cum within 40 secs whilst masturbating. It doesn't have any relevance with actual sex. We fuck like rabbits with my beloved gf and it almost never lasts shorter than an hour.
By the way, I had this ex gf where I simply couldn't last more than 10 minutes. It all depends on the harmony with your partner I suppose.
