Hi guys... I need your opinion (its not an opener haha)

I have met this girl from Hong Kong. 31 years old, really cute. We have met several times, firstly just friends, didn't find her too attractive but somehow her cuteness came out. Now, at some point I have gradually started my usual moves. But as friendly as she was, there was no response in terms of attraction. I stayed cool, but it did my head in. You know, normally you get positive or negative reaction, but she was as if she didn't see it (somehow I believe she didn't). At some point I though "oh fuck it" and I told her...."you know, I thing we should have sex one day"....
She was shocked, telling me that she didn't expect that since we are just friends ... haha trust me... I didn't act like one.
BUT.... then she said... OK!!! I dint quite expect that.
Well so we did.... but until that point she was cold.... and after we left bed she was cold... basically she shows no attraction, although she is nice to me. I know she doesnt sleep around, she is a decent girl. Never even saw her flirting with anyone...
I am not desperate, I see other girls, but it just doesn't make sense to me!
Any opinions??

So if I understand correctly, you did sleep with her? Maybe she sees you as a friend with benefit? The best way to know is to actually talk to her about it, or just keep doing what you do with her and you'll find out by yourself what she thinks of you, I personally think she likes you but is just shy, so act like nothing happened and be your usual self, she should open up to you sometime soon.

Well, we have talked about it before we actually had sex. I know she doesnt want relationship, neither do I. We made fun of it that we have a contract.... we are friends with benefits. That is not a problem. But what is striking me is how irresponsive she is... I mean emotionally. You know girls. I have had friends with benefits before, and still, these girls have acted in a way that shows attraction, desire, and so on.

This is not a complain lol, I am just surprised as in my years of dating and sleeping with girls I have never experienced something like that (Id call it "zero feedback"). I am guessing all the time whether she likes something or not... not in sex, but in interaction.

I am always myself, but still there is a range of ways to be. She is a mystery.... or a cyborg lol.
