I have this problem to were girls I casually date, end up falling for me.

This girl I'm currently seeing, knows my intent is just to casually date her/nothing serious.. and that we are both free to as we both please. She said she was fine at the start, but now is falling for me. I've been seeing her once a week for about nearly 2 months now, sometimes we've gone a week and half before seeing each other.

All we do is have sex (really good sex), watch movies and talk about stuff. This has happened to me in the past, and the only solution i can come up with is to solely become friends.

How do you guys go about casual dating and the girls feelings?

Well girls build the most connection with a guy during sexs. As u said the start falling for you after a few months of steamy hot sexs....

So i hope for you, that you will come across a girl who does not get so emotionally invested into sexs.
