I derailed a little from the main topic maybe, but I think it could help anyway.
To last longer you have physical and mental things you can do.
Physical:
- be healthy
- quit smoking and reduce alchool consumption
- train your pc muscles (Kegels)
- learn to know your body, masturbate till you almost cum and stop, rince and repeat
- when you feel the urge to cum try to not resist
- relax
- deep breaths
- change the rythm
- sleep at least 6 hours, better if 8
- eat healthy food, avoid meat and animal products
- do not eat too much before having your session
- walnuts, pecan nuts, watermellon and avocado can generally help
- try to be idrated all the time
- empty your bladder before your session
- if you suffer of constipation, eat more fibers, it will be easier to empty yourself and to relax your pc muscles
Mental
- relax
- enjoy the moment
- think temporarly to other things not sexually related (you risk to get limp)
- avoid being stressed
I probably forgot several of them, my “mantra” while masturbating (also when i have sex) is thinking at the three Rs, Respiration (breathing), Relax, Rythm (I offen get more tense without noticing it because I masturbate too fast).
You also should remember that human brain is not able to think at something “negative”. The classic example is “Don’t think to a pink elephant”, it’s impossible. So you should always say in your mind positive things like “I’ll resist”, “I can stand it”, “I’m strong”, “I can choose when to cum” instead of thinking “I don’t have to cum”, “I’m not going to resist the urge to cum”, “Do not cum”.
Even if you cum, and you’re still young, you should be able to wait 15 minutes and startover. If you’re older like me, probably you’ll have the opposite problem, sometimes you want to cum and you can’t, then when you finally are able to cum, you have to wait longer before being able to cum again. I’m 43 and am still able to cum at least three times in a day. When I was younger I could cum many times during the day, sometime even doing hours long sessions (I used to cum so much more then and even at 1 and a half meter away).
If you tried all of this without some benefits, I would talk to a professional. Have a look at some stats, you will be surprised to see the average time of sexual acts. If you think everybody does sex and lasts like in porno movies you’re totally wrong! Duration is overrated, quality should be more important.
Try finding some videos you like on Faptap, something about 15/30 minutes, mount your handy to have handfree, lean back and enjoy the moment, think at the three Rs and when you feel the urge to cum take some deep breaths, you’ll be surprised you’re still resisting, if not just hit the power button on the handy or pause the video. Rince and repeat.
Using videos you already know and that are not too exciting for you could also help.
I hope my words will help you
p.s. Italian is my mother language, be gentle if you don’t understand what I wrote. My three Rs mantra in Italian is: “Respira, Rilassati, Ritmo”.
EDIT: I can’t believe I forgot the most important trick (facepalm): when you feel the urge to cum, put your thumb and index finger (more if needed) and grab the base of your gland (the head of the penis, the mushroom top) and gently squeeze it (as a rubber band would do if around it), it should stop the urge to cum.
I would also suggest something to the partners masturbating/edging a man. Pay attention to the testicles, the harder and smaller they are (during the act), the sooner your partner will cum. If they’re loose and floppy cum is not about to come… pun intended…
