I cooked after his first sleep over. A full breakfast with all the trimmings. He was on cloud 9 and wanted to come over every weekend after that.
It did create a quicker bond but I wouldn't advise anyone to do the same; I was wined and dined less after that. I only did this for one man though. Although he's DH now, even that was a longer time coming than it should have been
I would say to give him a taste of your skills after a few months but only once in a while, just enough to get him craving more but not comfortable and feeling entitled.
