Moved to the US from a European country. Highschooler in senior year - working on getting a driver's license, can't drive just yet and it's screwing with my logistics a lot, gonna be at least another month until I turn 18.

Whenever I set up something, the girl is picking me up and I can see some slight discomfort in having them take charge, so to say. The only "date" I can take them on within walking distance to my house would be Friday night football games at my school, poor chances of isolation. Cannot isolate them unless its' by circumstance so this is a minus. Now my main problem is escalation is going great, I usually end up making out with them in the car (parents at home), they give out ASD, no problem, say something along "that's ok we're not having sex", backing off a bit then ramping up again etc etc. Then they just flat-out switch from hot and passionate to plain cold and start tirading about how "guys only want [them] for some action".

What's going on, and what can I do from my side to prevent things like this from happening again? How to cope with this handicap for another month?
