Not sure if its me or what but.. No girl I've ever been with has been able to get me off with head. It starts out feeling good but quickly diminishes and I don't feel much of anything after a bit. Unless they use a ninja-death-grip with their hand (which they say gets tiring after a very short time) it goes forever and eventually I end up losing it. My last GF of 2.5 years eventually got demoralized and gave up after many attempts (and yes, I provided feedback as far as what to do and not to do). The girl I was with this weekend got defensive "I've never had a problem with OTHER guys." Anyone experience anything similar?
