Why do people go crazy over kissing? Is it a mental thing? The physical sensation of kissing me on the lips doesn't titillate me. Sometimes when I'm kissed on other body parts (chest, groin, abs, insides of my thighs) it titillates me a little, but my partner goes crazy over kissing me on the lips. And when she's kissing me on the lips, sometimes I feel it goes overboard! Like I think once we kissed for 30-40 minutes straight! Our lips were chapped and we had both run out of saliva to wet them but she didn't care, she just kept kissing away. Why would she persist like this? What's so good about kissing? Is it a female thing?
