One who was nerdy smiled and said, "Yes" and pulled her hair back.
Another who I went on multiple dates with a few years ago (she was 18 then) told me on the next date, "When you asked to kiss me, I told my friends about it, and I almost wasn't ever gonna meet up with you again. Who the f--k DOES that? If you want to kiss a girl, go for it."
She just went off haha and made it seem like I was inexperienced even though I was six or seven years older than her.
