if you took a girl virginity then dumped her 15 minutes later your a cock!
But im not sure thats what you did. So you have the benifit of the doupt. PLEASE dont tell me its true and especially that you came to brag about it on some internet forums.
If on the other hand you ****ed your ex GF and then dumped her after getting laid i have no issues with that
PS. Red heads are stunning!
