When I wasn't a in a relationship, yeah.
If they are attracted to you, women will usually appreciate the confidence. Women assume that there is a reason behind the confidence so they get curious.
The problem is that you heathens make it obvious that you want to jump into their pants.
You need to be more subtle in your approach. Strike up a casual conversation, and attempt to make the woman laugh.
Not, "ayo ma, you looking kind of right in them jeans". The women that fall for that are probably not even worth the effort.
