I'm showing my crak in order for some people that are inferior to me and have sand in their vaginas know exactly what i'd like them to kiss. i don't want there to be any confusion in expressing that, unlike the confusion they have about their sexuality.
why are you looking at my ass? you are not only looking at it, but you must be obsessing over it because you are describing it's shape and thinking about anally violating my ass.
anyway, i wouldn't really say my ass is flat. it's a 2D picture in my avatar, so it's kind of hard to see the nice curves of my ass cheeks. i do have a nice ass for a guy, you can admit it, i won't think any differently of you.
