PS - If you're curious about norms, in my experience most women discuss STIs and sexual exclusivity before they get intimate for the first time.
This all the way. I know we are all grown and sex may be casual for some but for someone like myself, someone who has respect for a woman, who is looking for a respectable woman to have a relationship with etc., having sex so soon would be a huge turn off for me and there would be no way in heck that I would ever consider being serious with that person. I might go along and get caught up in the moment but once I thought about it all I would be like heck no, heck no! Hence this is why I think he hit you with the player question as well, it is just not a good look, especially with the optics of showing up half naked at his door. I know this is not your normal M.O. but I think this might have been a big reason why it didn't move forward, it's highly possible. And for him to do the same with regards to sexual advances so early with you should raise big red flags about how he is a man, is he a player? The same could be said on both ends. I know if you show yourself immense respect that you will attract guys who will respect and cherish you because you are such a sweetheart. Be good to yourself ok and the rest will follow naturally. Take care and good luck.
Been around since Sept 2019. Will post my sitch soon.
