How to produce more semen during orgasm?

first of all when ur about to cum stop and do something else like eat her out or play with her boobs and do that for a while and when ur ready to cum, cum and you cum a lot.

You can't produce much more on demand. But there are steps you can take to produce more during some sessions. I’ve been jackin’ it about twice a day for 40 years so I know what I’m talking about. There are only a few methods I have proved to increase semen volume:

1. Wait 3-5 days between orgasms
2. Drink lots of water
3. Look at porn for hours before you let yourself cum. Stop. Repeat a few times. Your prostrate makes more and more fluid the longer you wait.
4. Prostate message with a toy such as the Aneros Helix (haven’t tried yet; repeating what I’ve read elsewhere).
5. The through-the-pants method of masturbating. This method involves leaving your underwear on, and maybe even your jeans. Place the penis at a 45 deg. angle, angling away from the hand you will use to do the work. So, if you’re right handed, your unit should be pointed towards your left hip. Roll/rub your hand over the head of your penis through the material, either around and around or back and forth…experiment. Works best when you are about ¾ hard. You can also do this with the floor subbing for your hand: Lie face-down on a carpeted floor, again with your three-fourths-hard unit pointed towards one of your hips. Then you grind your unit into the fllor. (This is actually the first way I learned to do it…at maybe age 8. I called it “getting a feeling.”) Doesn’t work if you get too hard, or your unit will try to stand up and it’s just uncomfortable. Anyway, over the  years, I have found this method produces the most semen. About double the load of traditional jerking. The only problem is, all that extra cum is in your underwear! (If you’re doing it while lying on your back, it’s possible to hold your underwear away from your skin when you cum so that it all lands on your skin under your underwear, then you have to carefully remove your underwear so you can clean up all the goo.
