She can go for almost 4 hours?!

Am I effectively (yet ironically) screwed? That's what she told me. She used to say "You'll never meet a girl more horny than me" which, admittedly was kind of exciting to hear. But now she tells me she can go on for almost 4 hours? We haven't done it yet and I'm kind of frightened by the thought.

So,
A. Do I need to practice a lot more or else end up girlfriendless?
B. Is she bluffing? (she might be exaggerating but she doesn't outright lie to me)
C. I'm in for a good time?
D. I'm in for a very very bad time? (HOW THE HELL DO GIRLS EXPECT US TO DO IT)
E. I should become gay before she reels me in?

F. Just don't give a shit whether or not she orgasms. Make it all about you.
