If you are looking for a serious relationship then it’s advisable to date long before having sex. I regularly dated my now husband for 2 and a half close to 3 months before sex. I’d say if he brought up sex after two dates like this new guy you’d just met, I’d likely not date him any further.

First dates, weeks etc supposed to be about getting to know people, not get into their pants.

I am not saying you should wait 3 months but certainly I don’t recommend sex after just few dates. You don’t even know these people. Last one was married. So please pace yourself

In addition it’s quite dangerous to have sex before you know someone well
