Making a move on girls who talks too much seems SCARY

It's not that I am scared with every girl, it's like it's hard for me to make a move on girls who talk too much. Like I get this feeling : let's make a sexual move, and then I get scared and never make it.

But with girls who talk less.....I find it really easy to make a move. Heck, I'm even excited to do that man.

Or the girls who are my type are quite easy for me to make a move.....it's like I can't resist them.

I don't exactly know.....whether it is because I don't find them really attractive or not. I do find them attractive....but just because of their curves. But with the girls who are quite type.....making a move isn't much of a issue.

So, what's really going on here?

Let me know.

Thanks.
