It seems to me that “she” (her actions) is responsible for your orgasms. I mean, she decides when you ejaculate. Obviously you gave her control. So, if you have no control (no responsibility = no control), you will not be able to last/stand “her super orgasm”, because you’ve already made your decision.
As long as you choose to magnify her behavior (super mega orgasm), you won’t have control over your body (unless you change in “machine”, learn how to become multi orgasmic, or stop behave like a “puss” – your word by the way).
Of course the simplest solution is to choose, that you want to give her more pleasure no matter of your urge to finish, so you will regain responsibility.
There is just one condition. Stop being “puss”.
PS I see some good advice for lasting longer so I hope you at least learn how to use those simple tricks.
