It is a requirement for me. This rule weeds out those who are only in it for the sex.I'm not down with the no kissing on the first date thing.
I thought a simple kiss (so long as both parties are willing) is a polite and commonplace way to end a first date that went well. I had no idea it makes you a crazed sex fiend.
It's a slippery slope. You know how girls are, all in it for the sex. Some of us just can't control ourselves once we start kissing.
