Synchronized Ejaculation

A truly epic achievement which can be accomplished when masturbating to a familiar pornographic scene. The masturbater achieves synchronized ejaculation when he ejaculates at the same time as the man (or men) in the video. This cannot be accomplished with lesbian or all-girl porn.

Joe achieved synchronized ejaculation and then high-fived everyone he knew with the hand that wasn't covered in ejaculant.

flaccid ejaculation 

When your penis does not have enough time to get hard...it goes straight to ejaculation. Usually used when in intense excitement.

I just had a flaccid ejaculation when Kelly Kelly walked by.

post ejaculation clarity 

The minutes and hours after ejaculation when a man's brain becomes very clear and he is able to reflect, plan, and make difficult decisions without his sexual urges clouding his thoughts and judgement. It is also known as post nut clarity .

Brendan: Yo bro, I think I might marry this girl! She's all I've been thinking about all week.
Joe: Whoa!! Slow down there buddy, how about you think about this after jerkin off? Trust me, the universe appears completely different when you have that post ejaculation clarity!

ejaculatory inevitability 

The point during sexual intercourse where the male realizes he is about to cum (ejaculate) no matter what he does to stop it. Usually at this point semen has already entered the base of the shaft of the penis, so the male cannot stop the ejaculation process no matter how hard he tries.

Grunting and groaning and kegeling didn't help he had cum up his shaft and he was at his point of ejaculatory inevitability.
