Increase cum amount

Get one of those big syringes like you use for getting medicine into an infant. Freeze about three loads of cum. For the fuck session you want to shoot a big load thaw it and fill the syringe with it. Inject the cum load into your urethra (the end of your cock) and begin fucking. When it's time your prostate will release all the cum it has plus push out what you have injected. Walla! A big load as much as 4 normal loads.

Now seriously you can do all of what has already been suggested but unless you have a oversize prostate gland ala Peter North, you're only going to eject what the gland can hold in storage. If the prostate can hold 5ml of semen that's all that will come out. If it's 4, then no more and so on.

 

Definitely stay hydrated.

 

Hydration , edging and prostate stimulation always made for a good healthy load of cum.

 

I am almost 63 and still shoot quantity loads. As others have posted it is important to exercise stay healthy and hydrated. I cum 3 to 4 times per day in and on the wife fwb and fb and wanking. The first ropes of the day are much more than the later ones but my wife and fwb are into more quality than quantity. My bi-fb enjoys a nice load in her but also on her because her ex husband came in loads. That said she enjoys multiple orgasms and as long as I stay hard and can perform that is most important
