I think sex without marriage - Pre martial sex is mainly focus
onto body pleasing and feelings.
Of cos the pleasure will definitely be satisfying.
But what happens after 'it' all came to a climax and ended
there.
For me personally....i felt empty....at times guilty.
Sex not only affects our pleasure point. But more importantly, it
affect our emotional aspects subconciously.
Worst could be either party being emotionally chained onto the
other after thinking that sex could bring a r/s closer. Well...it
could be possible...but not for long.
However having sex after marriage could be one of the most
pleasurable feeling (ideally)
Because not only two person knows that sex is fun and it feels
good. They know that they are going to be together for the rest of
their lives. The focus here is not only on physical...but the heart
of all matters. The possiblities of Sex within marriage is
boundless....children....family. love, care, concern.
The catch here is big C - Commitment
*shivers*
Subconciously(conciously), both partners are able to experience a
greater depth of what is called 'knitting of two hearts into
one'
That experience is something which i don't think Pre martial Sex
could ever bring. Ever....
Cheers
