Is that all you guys got? help!
Seriously McPendo,
Even married couples are not always in the mood to display physical intimacy toward one another. And here you are worried about a MERE girlfriend.
Many times we're not aware of the hidden messages our own body language is sending. If you keep on whining and stressing over why you never got that kiss......the desperation is going to start showing on you dude....and that might turn the girl off.
Besides....wouldn't you like to be kissed because the girl actually WANTED/DESIRED to kiss you? Or would you rather be kissed because the girl felt she HAD to kiss you when she didn't feel like it? Isn't the former better than the latter? I think so.
