Well, this is my opinion and does not represent buddhism in any
way.
Human sexuality or lust is not something very wrong or bad.
It should be dealed with kindness. Obession with sex SLASH
Obession with anythings else can create a lot of
problems; such as - lack of mental clarity, compulsive
behaviour that become out of control and carry out sexual
misconduct acts that lead to emotional and social
problems.
If you have this problem, then it is good to go seek counselling
or do some chanting like Namo Guan Shi Yin Pusa or practise
meditation regularly.
As i have quote one or two months ago...
“ Lust is managed
with right view regarding sexuality. Right view regarding sexuality
is based in the perception of what his harmful sexual conduct and
what is not. If we do not have a clear perception of what is
harmful and not harmful in regards to sexuality, it will be
difficult to manage
lust.”
One has to practise to a certain level, then
will they be able to manage and eventually cut defilement
lust in a natural way and not on a repressive level.
Btw i don't think Buddha mentions Kundalini in the
sutra?? but it is probably good to know something about
it.
