Oh yah.. i think i found what i want to know liao ...
the following:
When a man becomes sexually aroused, blood flows into his penis and
testicles (or balls). If he ejaculates, the blood flows out of his
genitals more quickly than if he does not ejaculate. The discomfort
men can feel when they have been sexually aroused but have not
ejaculated is sometimes called "blue balls".
Although blue balls can feel uncomfortable, the discomfort goes
away fairly quickly. If a man is extremely uncomfortable, he can
masturbate (or ask his partner to masturbate him) to orgasm.
However, there is no danger and no pain if he does not reach
orgasm. So, guys who say that they are really suffering and must
have vaginal intercourse to relieve their blue balls" are not
really telling the truth.
heeheee.... okie... guess case close for the moment.. i really hope
it isn't an unhealthy issue ..
