Gotta keep shit interesting on all spectrums of a relationship, doesn't have to be every day but I'd go w/ #2. It seems that the year mark is the real test if a sex life is going to continue with a girl. Last relationship, it died after around that time. Everything else in the relationship got more stressful (I blame part of it on that) and I broke up w/ her.
I'm staying away from letting anything develop into a relationship with girls these days though. My life hasn't been this stress free in years!
