Many people and countries with their belief and tradition but on a closer view (apologies to the S.U's) bt u'd see sum treat d person they are engaged to like a leper afraid or avoidin skin contact u'd neva even know cept u 're told so my question is it actually a Sin to Cuddle or kiss a person u're engage or to be married to. Cus in abroad it seems to be a norm for d average christains there.

it is ok to do anythin with the one you love, or with anybody who is willing to do anything with you. the fact is that we should try to avoid anything that makes us guilty so that we can live a stress free life.

Yes and no. Why? Kissing just like hugging can be used to show affection and fondness in which case it is not a sin; the fact that one may gain an erec¤tion or sensual pleasure in the course of doing same nothwithstanding. So when the sensual pleasure is a consequence of kissing done innocuosly, then no sin has been committed. (This happens mostly in ordinary kissing as opposed to french kissing.)
BUT when a person kisses not as a sign of affection or fondness but with the intention of gaining sensual pleasure, (especially in french kissing) then to my mind a sin is committed.
HOWEVER, it is usually counselled that members of the opposite sex who wish to remain chaste should abstain from exhibiting such signs of affection especially when alone lest they be overtaken by lust which may lead to engaging in the main act.
ALSO, one should understand and guard over oneself, as man may even gain an erection just by chatting or holding hands with a female.
Prudence and discipline should be applied always.
Shalom!

its the intent that matters. Whether positive or negative

Someone to be married to is diiferent from someone you are married to.This simply means, you are not yet married.She cannot be called a Mrs.

If you have a money in the bank,u cant spend it until d necessary transactions and verifications are carried out.

You can not drive or own a car because you intend to buy it in d future.

As long as you are not married to her,you have no right to cuddle or kiss her.
If people that were once married could be seperated or divorced,though against God,there is no 100 % assurance that you will eventually marry someone u wish or intend to marry.
Sister "A" was cuddled and kissed( Romanced) by Brother "A" for 6 months but was jilted for a cogent reason(s).If she gets to know Brother "B" do you think it makes sense for her get attached emotionally again.?When u kiss and cuddle,u are expressing ur feeling for each other, and for d women ,they are emotional to this than we men.

Another point is as said by Jesus in Matt 5:28" But I say "But I say unto u ,that whosoever looketh on a woman to lust after her commited adultery with her already in his heart". Since the marriage has not taken place,and you engage in romance,that is a lust and it a sin.

Most people avoid romance or cuddling to avoid falling into temptation.
James 1:14" But every man is tempted,when he is drawn away of his own lust,and enticed.Then when lust is hath concieved,it bringeth forth sin,and sin,when it is finished,bringeth forth death."

To avoid falling into the very act of fornication,it is betther not to get yourself in the mood.So it is advisable to avoid it completely.

Since the intention is not not make love,then there is no need for a romance,or kiss and hugging.
There is no need to sniff the food you do not intend to put in your mouth.

Thanks.
