I did not read all pages so sry if my answer is a little off .

As a man I like to pay for the 1st date .. on the 2nd if the girl insists I let her pay .But usually I enjoy paying ,I like to take care of my gf .I have some friends that said they want a girl that will provide for them . I dont agree with that at all .
I do like to see a girl trying to pay , or reaching for the tab .. but unless she really insists I dont like to let her pay ... maybe i would say something like : You can get the next one if you would like to go out again

And regarding your thought on ""I can t invite him over for dinner cause he thinks about sex .. ""you are probably right , I would think about that if a girl would invite me at her home for dinner ..

But then ( i dont know about other men ) im not stupid .. if you just want to invite me over your home for dinner .. and you accentuate that its only for dinner I ll get it .
