Girls can look at the man with whom they are planning a serious relationship for quite a long time. I myself am the same. I feel attraction after a long time, several months, but this attraction is strong and long. Perhaps the girl has something similar. Or you, too, must take a long time before you want to spend time with a girl in bed.
I understand that everyone has their own experience in such matters, I personally have such. I never chased after sex, I tried to get to know a person as close as possible. But if you are uncomfortable in this mode and you think that you are wasting a lot of time - give yourself and the girl a chance to find a more suitable partner. Good luck
