I am a hugger and my primary LL is physical touch. I regularly hug men and women publicly who are friends. What kind of hugs? Both side and front hugs, depends on the person, the level of friendship, occasion, comfort, and their "situation" and/or emotions, etc. And as others have mentioned, I'm keenly aware of how I am around those who are in emotional distress, especially if they are single or in a difficult time in their marriage.
Not a fan of the I KISSED DATING GOODBYE/courtship thing (but I always appreciated JobMan's approach on the old TMB board). On the other hand, having and setting healthy boundaries when dating is critical along with filling one's mind with Scripture and good things (Phil. 4). When DW and I were dating, we were grown adults but we still had to set boundaries and make adjustments as we continued to engagement and marriage. I appreciate the sentiment of not kissing or the "long hugs" but I'm sorry, if someone thinks that is gonna stop one from lusting, I'd like to try some of what that someone is smoking (especially on those hard hormonal weeks, actually LACK OF hormones is probably more accurate, my wife has due to menopause! Many times simply breathing can bring on some wrath. Haven't experienced it? Don't believe me? Just wait and see.) Lust comes from the heart & mind of the person so physical affection isn't necessarily a direct correlation.
Don't get me wrong, being pure and honorable is a good thing. I didn't kiss any of my dates (defined as went out with 1-2x) I took out as an adult after my divorce or those that I dated (went out 4-8+x over months) until I was intent on what the future would look like with them and that included meeting my youngest son (there is a story or two floating around TMB explaining that standard). I was divorced for 13 yrs and dated 11 of those years. I only kissed my now wife and the one before her (kissed her once and she broke up with me a week later with a txt in the night...weird).
One will never regret being pure and honorable. My concern would be for those who grew up in that culture and legalistic church situation, especially the women, will they be able to "flip the switch" once they get married and enjoy their sexuality with passion....or will they remained closed to God's design for sexual passion and union in marriage?
