It could be, but probably not, especially during the summer. Also indecent exposure charges could be difficult to explain to your parents who you are both still dependent on. I understand the desire to have sex everyday but realistically paying for a motel room once in a while isn't expensive, relatively speaking, even with a minimum wage job on the side (especially if you're still living at home). It is desperate, but legal.

The only way it could be a shit test would be if she was using the car-sex-despair as a gateway for you to spend money on her. Though if I were to wager a guess, it's because she doesn't want to get sweaty, because she wants more room to fuck you, she doesn't want to face legal repercussions and/or because she wants more privacy.

Options: get a motel room, get an apartment or request a "closed door policy" with your parents.

Yeah, the car thing does have its limitations - and it doesn't say much about your "value" if that is the best you can do or the most resourceful/creative you can be. How about you BOTH make contributions for a motel room? Or, you could go camping for a weekend.

I just was driving by two lovers making out on the street and it reminded me of this post. "GET A ROOM!"

However, the other day she had enough and said she wasn't comfortable hooking up in the car anymore. Personally I think this is just a shit test...

Sounds like something that has the potential to be a legitimate concern.

A "shit test" is more of something that has no substantial impact on anything, but is mostly an attempt to rattle you. In this case... well, fucking in cars isn't all that comfortable. You said it yourself, speaking for yourself.

if she's legitimately uncomfortable what are my options?

Ummm... you tell me... What are your options?

If you think she's possibly LTR material, and she has a legitimate concern, see what you can do. Let's not ditch the idea of fucking in cars, but if her concerns are legitimate and you address them, maybe you can do a hotel room, nobody home at parents' house, and a car? I wouldn't buy into the idea of never fucking in a car... but I wouldn't treat this as an "all or nothing" thing, either. It doesn't sound like a shit test, so I wouldn't treat it like one. I also wouldn't treat it like an ultimatum... whatever she said... I'd treat it like a preference and see what you can do to accommodate it.

Do you have close friends (male ones preferably) that could help you out? Ask them, but don't be a dick and do it frequently.

Don't know about how it is in America, but in Turkey we have houses that are rented daily for a reasonable price, which people use for sex.

Edit: Oh, almost forgot, being a friend with a realtor will eliminate this problem for you. Try to be friends with em.

Your family probably wouldn't care if you kept it down. My brother and I fuck girls in our house, both our rooms are above the kitchen and you can hear the springs going, but as long as you aren't obnoxious and moan nobody says anything.. You can hear my parents bang too, which, after reading TRP, is kind of heartwarming.

Just don't be ashamed and tell her they can't hear anything.

As for her complaining, just watch this
