I’d stick to after she’s converted, generally:
How to Convert One-Time Sex into Regular Sex
If it’s the first time you’re together, this will usually backfire unless she’s REALLY turned on and you’ve set an extremely strong sexual frame… to the point where basically it’s obvious the two of you will shag and she’s expect some aggressive, wild sex.
If it’s not your first time but she isn’t converted, ditto. She won’t be down for this yet.
Instead, wait until you’ve already slept with her on 3+ occasions and she’s firmly converted. Then you can use the strategy from the “raw sexual enthusiasm” article and have it go over well.
