I (25F) am seeing this guy (27M). I feel like we have a lot in common, but there is no passion. I also find it a turn off that he is a smoker and is encouraging me to smoke with him. (I am a former smoker myself so this is very triggering)

I just wanted to ask if this is okay in your opinion. I know that many women leave good men for silly reasons and then end up alone. We have only been dating for a couple of weeks and we haven't had sex yet. I am not sure if I should have sex with him hoping that it would increase our chemistry. Should I have sex and try to fix our lack of passion or should I just let it go if I feel nothing?
