Dude agreed. Take her out drinking, both get a buzz. In addition to your usual stack of gear, one hour before the rendevous, take 100 mg of Viagra and 10 mg of Halotestin. After social hour, fuck her brains out... You make her cum 5 times without you nutting until the end and she will come back repeatedly-- I assure you. Fuck dude just pretend you are doing an abdominal workout. You'll last at least 45 minutes!!!
Incidentally the Viagra/ Halotestin combo works great. You might get the feel of a retrograde ejaculation-- which is a new sensation for you, and you will have some huge loads-- she'll
Then dude whenever she gets horny she'll think of you and compare any other sexual experiences she had to yours. Show her you are in control.
Lift, fuck, make money
