You didn't read my post correctly.

You don't ask her if they want to go home with you. Never do that, never give the girl the power like that. Think of it this way, if you say do you want to go home with you, in the girls eye's you're effectively saying, "So are you an easy slut? If so it'd be great if we could go back to mine, maybe? Please?"

You might as well cut your dick off and throw it into her drink - that's the only way you'll get it wet.

Be the man, lead her home.

Between kissing her and taking her home, just tease her. Bit of push and pull, take the piss out of her etc. Maybe go to the toilet after saying you'll be right back and leave her just a bit longer than you'd expect - she'll be wondering where you've gone.

If you go blank it's a confidence issue. To get over this you must stop giving a shit.
