Some terminology: When a man experiences an "orgasm" he "ejaculates" or squirts semen containing sperm out through his urethra. The vulgat term "cum" or "come" is frequently used instead of either ejaculation or orgasm. Cum is often used to mean "ejaculate" or the stuff you squirt.

There is some point in male sexual arousal beyond which the ejaculation is inevitable. Usually about ten seconds before the orgasm starts. If a male is interrupted at that point, he will still ejaculte (cum) but the pleasant squeezing that cause this to squirt will not be experienced.

I have stopped while doing a hand job and had a guy squirt all over. Disappointing that I did not keep it up.

I assume you are a young male. I do not what you are calling cum and what you are calling orgasm. The male orgasm includes ejaculation which means that semen will ssquirt out of the penis. With men, you always see the result of the orgasm.

Now, the exception. There is a phenomenon known as retrograde orgasm. This results in the ejaculate going up into the bladder rather out the urethra. For some men this how it happens regulary; for others only once in a great while. If you retain your ejaculate by tightening up, vokuntarily or involuntarily, and still have the muscle reaction of a "normal" orgasm, the semen has ended up in your bladder and you will likely have cloudy urine the next time you go.

Hmmm...Could be possible...I once was masturbating...and...my dad walked in just as I was cumming ...and I cummed but without a orgasm..Cuz he scared me
