Honestly, Lois Lane's presence in Clark's life is like one of the few things that made Clark smile and relax in MOS and people were complaining things were too gloomy for Clark at times or that there wasn't enough Lois and Clark stuff in MOS. I say, embrace the positive influence that she has in his life and allow them to flourish in the sequel.lol
Also, one thing that i noticed from seeing the kissing scene again from my previous repeated screening of the film was how Cavil and Adams really used their eye contact and facial expressions to really map out on how the characters were feeling without them actually having to say it, in particular, if you look closely, you can tell that Clark is kind of asking permission if kissing Lois is alright with her by using his eyes and she responds with her own eyes saying yes...and then when he gives that line about how he believes that the whole "going downhill after the first kiss only applies to human beings", Adams has Lois jump right back into the kiss after hearing that from Clark.
