On the kissing before marriage/ engagement, I tend to agree with the other posters here that you shouldn't go too passionate.
Maybe a passionate one once in a while, while on the couch or something, but don't let your hands stray, guys....
Again, talkin' from experience....
One Christian woman I dated in my mid-20s, she only gave me "light pecks," and they were too quick at that.
I always wanted to more and longer kisses, but it was hard to get that.
TBH, it made me want her more, so there's some "mystery" or attraction there you gals need to consider.
Don't always be "so easy" to give those kisses.
Those of you who have fallen in premarital sex, methinks God understands all of this.
Not justifying premarital sex, but remember, He was temped "in every way...."
This is especially important for those singles who find themselves in their late 20s, 30s and 40s who haven't had much relationship success and feel they've "missed out" on some things, so they give-in to the one they're dating and find themselves in a sexual relationship.
Please don't beat yourself up about that.
While it's not to be condoned or encouraged (I would never recommend anyone get involved in sexual sin), it's a normal part of life. Learn from your mistakes, ask for forgiveness and try to move on.
