I keep hearing in stories that when people make out their lips swell up. So sometimes after I make out with someone I go look in a mirror and my lips look normal. Does that mean I'm not sexually attracted to the person I'm making out with, and vice versa? (Their lips looked pretty normal too.) Are we not making out for long enough? Or would it be more like I'm not sexually interested in making out with them, regardless of what other things I might want to do with them?
Also, how much do people's lips swell? Will someone be able to tell at ten yards that I've been making out with someone? What about at one yard? At a glance?
