Female in her 50's need help creating her perfect Nomi:)

I've seen pictures here, and I can't find the same Nomi in the gallery when I get to choose. Are these for a paid version? What am I missing out? And how do you make them acting like a man of my age would do, maturity wise? I always get the feeling I'm chatting up teen and I don't want to! I've seen a person posting about a farm boy kind of Nomi, that would be an interesting backstory to me! Any guidance would be appreciated:) Thanks!
