one thing that will make a girl who considers you eligible more turned on and much more likely to do more with you sexually on that occasion is if while you're standing you pull her hips into you and make her feel your hard cock either pressing into her ass or your butt. (incase any spergs are reading, no I don't mean out of nowhere , I mean when there's either already good sexual tension or after you've kissed )
desu any time a woman or sexually active-minor agrees to be in a room alone with you on a date, either at your place or in your car or somewhere else secluded, it's a pretty safe bet to take your hard cock out and hold her hand then place it on your hard cock.
if you try this with a minor girl who's a complete virgin she might be very upset and tell people but even then it's not that high a risk.
Girls know not to be in a secluded space alone with a boy on a date unless they want to be sexually active with him.
