First “times” having sex

I just wanted to ask , what are good ways to help out my sex life?

I just lost my virginity and my boyfriend doesn’t have much experience either but I wanted to know any advice because in some positions I don’t feel much, and it’s because we don’t really have time or a place to actually have sex but a car, I lost it on a bed and it did feel different, does anybody experience that sex in a car is super different then on a actual bed? I’m so new and we have so much to learn but I just wanted to hear some people opinions and actual stories !😌I know as time goes and we actually have time to do it on an actual bed it’ll be better because there’s way more room especially because I’m 5’4 and he’s about 5’10-5’11😩😂
