I recently moved to the US, and it's my first time dating here. I have gone on multiple first dates (~6-7), and they have gone well, I'll have a fun time with my dates, and we'll decide to meet again soon. But when I text them after a couple of days, I'm mostly ghosted. What am I doing wrong? I haven't been able to escalate many of my dates, and they have always ended with a hug. Is the lack of sexual tension the reason?
