2 is beautiful. A little slender, but beautiful. A wife.
3 is very pretty and is also working with a little boobs there - but spidey sense says something's missing. A girlfriend.
6 is attractive and looks submissive - but something in her expression says probably not much convo. A lover.
4 and 5 ... just no.
1 - been there. Makes me feel tired just looking at her... Maybe if I was just out of college.
