ghee..i tink pre-marital sex is fine in a serious n steady relationship  i bet most of the couples these days got hook up with sex.its a common thing.i tink majority do practice pre-marital sex..

If you look at marriages nowadays, sex after marriage also does not have long relationship....lol.....

woyoo ..... stress nya ..  ...
Sex before marriage ...  most guys in the world today ... would say yes ... and a very small countable number .. would abstain ...
as for girls .. atleast half the women here in malaysia would have pre-m sex .. let me gtry and give u a few points favouring this ..

1. U get to see each other naked ...  Ucan tell if u find each other attractive or not . attraction is important ..

2. U get to test drive the equipment .. and ensure that everything works well .. i'mportant .. can see if partner is healthy ...or not ..

3. get to see if sex is good , bad , just okay , horrible, bla bla bla .. i'mpornant for a healthy relationship..

4. for girls ... when u have sex with ur partner ... initially he will be all horny and jumping on u like an animal .. but after awhile .. he will tone down a bit .. and U will get to see who he really is ... I mean .. like .. he will be more sayang sayang .. instead of just trying to fark u all the time ..

5. if u don't like sex with him ... or her .. u have the option of ending it .. if ur already married .. ur screwed .. in away ..

6. sex builds closeness and strengthens the bond of the relationship ... U try and kacau and see a long term couple .. bf or gf ... the partner will come find u and kill u !! ..

IMO .. the pros outweigh the cons in sex before marriage ... 
yea yeah ..some idiots might say that sex is not everything la .. this la that la ... ask those idiots to show u a young healthy married couple who dont have sex / or dont enjoy the sex / or who claim that sex in their relationship is not important .. and that they are happy ....  show show ??!?
bullshit !!
Good Sex = happy healthy relationship
bad sex / no sex = either partner is gonna cheat / leave / miserable / unhealthy / depressed / mentally ill ..

then must have bad sex for long term one is it ?
          

as long as it happen with the one i really love,it doesn't matter for me before or after marry.

if you can answer me what is love then ill tell you how.

It is normal for now a days having sex without marriage.
If you are thinking that after marry than have sex, then sorry, your partner will leave you.
