Sometimes girls get attached. It’s just in our nature. God or Darwin or whomever needs to explain to me why it is okay for us to release oxytocin (the bonding chemical) while breastfeeding AND after sex. That’s just not fair! At any rate, this girl could feel bonded to you, or she could be addicted to the phone sex. It may be because you’re so damn good at it, but what’s also likely is that her life is empty and she’s needy for something to fill the void. You’ve got to set a boundary and stop the phone sexytime, sir. It’s only going to get wackier unless you stop it.
