I like showing off online, did it since since I was like 14 on various blogs on Tumblr.
I stayed with my "uncle" (not actually related just my dad's best friend) for a summer because my parents went on holiday when I was 16, he works in it and somehow found out that I was posting nudes of myself online pretending to be older.
He also saw my posts about wanting to be fucked by an older guy and offered to help, I obviously said yes so he took my virginity and we fucked a lot that summer. Turns out he was into some kinky stuff, I let him tie me up and piss on me too.
Now I'm 17 and he's still the only person to ever fuck me.
Other than that the only sexual things I've done is sending some custom pics and videos to older guys for some online gift cards.
