On a more serious side to the post above.
I know plenty of guys who will take a 2 second glance from a woman as a come on.
I'm hopeless, I'm a total introvert and I have no idea that a woman may have any interest in me.
If a woman knocked me over, ripped off her clothes, ripped off mine and jumped on top of me I'd start to think "maybe I could be in luck here" .
From this reason I've often ended up with women who are outgoing and assertive
I don't feel bitter or put out by this, I realise this is just the way I am
