In the immortal words of Robin Zander (Cheap Trick lead singer), "I want you to want me!"
Our most sensitive errogenous zone is between our ears. My lips are hard wired into my brain, which is then hard wired into my dick. Kissing tells my brain that you want me to fuck you, therefore my dick responds. I can get there without making out, but you have to work a lot harder. And if you can make me believe once I'll keep coming back.
While we are on controversial topics, what about perfume? I know most ladies avoid it because of concerns about the client's SO, but god damn, a woman who smells sexy can have my debit card. Lol
