"two-stroke" is the term used for a male who does not need an exceeding level of sexual stimulation to reach climax.
The origin of the phrase "two-stroke" comes from mechanics, but has been cleverly adapted to mean
literally someone who only needs two strokes of
the penis and they're done. The most common usage of the phrase is as a nickname.

3) Well rack me off and
