This is a cool topic something I like talking to people I meet on-line. It turns me on to hear about the first time someone ( mostly females) had sexual feelings.... what they were doing an how they explored their new found feelings or sexual "tingling". Also the first time someone cheated on their lover. I could go on for a while about other stuff but I will list some of my fave turn ons.
Exhibitionism - from just a little to much showing, like legs open panties showing. top loose showing some boob. Or out right exposure, spreading legs when someone is looking.
PDA, between dad an daut. mom n son, flirting, touching between legs or feeling chest.
Girls dressed sexy / slutty, moms that dress their dauts slutty for attention from men.
"Dirty Little Girls"
Sexy panties an other underthings
Little girls with big boobs. Girls with flat chest are very sexy too.
