Car sex

If a guy wants to do anything intimate in a car does it mean automatically that he doesn’t like you? My parents said the guy I’m seeing is using me be he let me give him a BJ in his car (they don’t know literally that I gave him a BJ obviously lol they just know we did stuff in his car), and I said I don’t see what’s wrong with it bc I’m not allowed to have guys over, he originally asked me to go to his place & I didn’t want to go to his place by choice, and we didn’t get a hotel bc I don’t see the point of either of us booking a hotel when we’re only going to be together for a few hours max and not the whole day. The reason we weren’t spending the whole day together is bc I’m not allowed to see him due to my parents not meeting him yet & our age gap (we met at 18 & 27 but we didn’t know eachothers age until we were 20 & 29 since we didn’t talk as much and we are currently 21 & 30). He’s the only guy I’ve been intimate with before it happened and my parents know that so if I was gone overnight it would be obvious where I was & what I was doing. I asked them if they would feel the same way if they met him & we were the same age and they said yes bc “a man picking you up to have car seggs or even spontaneously doing it in the car is no better than doing it in a dumpster or public bathroom bc it’s a dirty environment in public and there’s no romance or thought”. My sister is very sexually liberal & participates in hookup culture and has car sex herself to this day and even she said “don’t lose your virginity in a car” and when I asked why she said because it was disrespectful. She didn’t say sexual acts in a car such as oral were disrespectful unlike my parents, but I’m still confused as to how it’s wrong to lose your v in a car when I would literally be doing it by choice and it’s not an issue of him not wanting me over or not wanting to book a hotel??? I really don’t see what’s wrong with car seggs, even if it isn’t romantic I feel like that should be your choice and that just because you have done ‘non romantic’ sexual things that doesn’t automatically mean he doesn’t like you?? My parents literally said that “only whores have car sex’ Like I don’t get how that makes any sense tell me if I’m wrong???
