Nudes

So I was on omegle (was bored) so I was chatting away with this guy and we had a real connection. We eventually went on snapchat where he sent me pics of his dick and I of my boobs and vag. Then all of a sudden it's like he lost interest in not only talking dirty but just chatting in general. Anyone else, experience the same, that a guy can seem cool and exciting and once he's seen you bits he doesn't give a damn?!
