have any of you had this experience?

Sometimes when I'm feeling extra horny I know I'll blow my load within 2 minutes with an MM so I jack off just before the session, "shoot airplanes" for Cantonese speakers. Sometimes this strategy works well and i can last a long time. Other times it backfires and i can't come even after half an hour of hardcore drilling and the girl is pissed as hell. Or even worse case, i can't get it up and look like a fool. There are even times when after jacking off, i don't feel horny anymore and don't feel like going for the session i booked. Does anyone here have similar experiences?
