Should i be ashamed?

So I met a new guy last week, and like most he is married k**s and needs to be discrete. I mean i know all i can do is be some guys booty call when the wife won't give it up, but should i be ashamed.
Last week i met this guy online, says wife not giving him any, he dont want to know me or kiss me, but needs to fuck. So we meet up in like the middle of his corn field, its dark, all he says is turn around. Now im dressed in knee high boots, a pretty minidress, and i turn around. He bends me over my car, nothing more said than turn around starts rubbing his hard on against my ass. Next thing he is inside of me, just humping the shit out of me. About 3-4 minutes later, he just grabs my shoulders hard, and i can feel his cock pulsing, he is cuming in me. (filling condom of course) He finishes and smacks my ass, and leaves.
Now it was fucking hot, he has not messaged me since, but this guy just totally cheated with me, and noone will ever know it.
Should i be ashamed? or does this world just need sluts like me?
