make him nervous

Lindsy • 💎Every girl deserves to be told how beautiful they are💎
So recently, this guy and I tried to have sex in his car one night and it wasn't working (I don't blame it because he is 6 foot 5 and well he has a tiny car). Anyway, we tried again when we were at his house a few days later and it didn't work again and he said "you make me nervous " 
Now I know this guy slept with a hand full of girls but is it because he isn't into me or do I make him nervous like... he likes me. Everyone always pointed out that he always had an eye for me but he is still hanging around his one ex. 
It ended up working but it's been stuck in my head and I'm over thinking. What do yo guys think?
