Here is a simple idea for seducing your female love interest. If you give her a romance novel, which you have read and understood, and is as close to your own scenario with said love interest, set up the same sexual tensions or settings as the book. When she is three quarters through the book and totally absorbed by it, make your move. She is probably hot and bothered with defences down. She will have a one track mind at that stage.
If you wish to seduce a male, give them an appropriate (straight or gay) magazine and leave them alone for a 10 or so minutes. At the point where they want a private moment to masturbate with the visual stimuli, make your move.
It isn't that hard to do, humanity doesn't need many excuses to have sex most of the time. Giving them stimulation in books and magazines saves a lot of time, effort and money.
We all know that people's frontal lobes usually shut off when they are sexually aroused, so they become temporarily stupefied. So if you do it, make sure you prevent disastrous forms of stupidity.
