For most men, sex on the first date means you’re too easy. No real challenge. NEXT!
Get the picture?
It also means “wow she’s done it with me so easy, Lord knows who else!”
Last but definitely not least, the loss of respect. Why call you in the morning?
Then you have the men who want sex on the first date, and if they don’t get it, they move on.
You have to take a chance and just be you. Not try to make them happy and go against what you would normally do.
