Who and what she's done before you can into the picture should be of none of your concern. Do like they would do on the kung fu movies. The young nigga would go seek out the drunken master, the unassuming dude in town, or the abbot to learn a "two finger-hella-kick-your-ass crane style." You should do the same.
Since she's had more experience than you, take this as oppurnity to learn new "styles," and explore your sexuality. She shouldn't have a problem with sloppy facials, finger poppin' herself in front of you, exhibitionism, booty chewin', ATM's, menage action, recommending high quality adult entertainment, how to satisfy her and other chicks, what spots to focus in on during cunninglingus, going to freak parties, or the freak club, and having out and out orgies.
Babygirl has unknowingly and unsuspectedly raised the bar on herself, and you rightly should expect her to go "above and beyond," with no hestiation." Every time you fuck she sould be your own personal "Carmen Hayes," anything less is unacceptable. If she isn't sucking and fucking right, use it as a neg and say something to the effect of, "you would think with your experience level that your skill set would be a little better than what it is.
