There are some good-looking and/or some sexy girls around. The only good-looking or only sexy are like 4/10 to 7/10. There are some good-looking (I mean their face) + sexy (I mean their body and the style of clothes) and I rate them 8/10. It's very, very rare to see some which may be a ONE-IT-IS but in the recent 12 months I saw two. The first one was with a perfect slim body, long black hair,... almost 9/10. And the second one I saw tonight -- shorter than the first one, with very pretty face that makes me feel I would be happy forever to watch her. I still can't forget her and I dream to meet her again but I don't believe I will be that lucky. Well, this one was 10/10 according to my taste.
And here is my answer: if we're talking about 4/10 to 7/10, I think I'd like different relationships (one by one, to be no cheating). But if it is that 10/10 or even the 9/10 one, I wish I will be only with her. And if it's some of those 8/10, well then depends on the character mostly.
