Does size matter?! This was a joke, but I felt it was worth picking up. Within the context of an exclusive life long sexual relationship your partner is your standard of beauty and body composition that God made for you. Within marriage you can enjoy the adventure and exploration of enjoying each other free from false comparisons. So size can bless... but then 'its not the size of the fish - its the motion in the ocean'...?! haha. The most import dynamic for good sex lives is commitment, trust and exclusivity in marriage built on faith in Jesus. If I'm willing to die for my partner, can I sleep with them?
If you are willing to die for them, then you should marry them. Then you can sleep with them. Should Christians go to the safer sex ball?
Questions to consider...
What are you living for?
What are you trying to build with your life?
Does this help or hinder?
I'd say given the levels of alcohol consumption and nakedness that I would not go because it would be both unhelpful and unfruitful. Is passionate kissing ok if you're not married?
In the Church, if you are not married, you are brother and sister. How do you kiss within your family? I know this might depend on where you grew up but its not normal! She/he may marry someone else. How would you feel to be at their wedding?
