I have done something like that. Sometimes when I couldn't climax, instead
of having her 'help' me, I would wait until later in the in the day, or the next day/night, whatever. Could make for a VERY frustrating time. The good thing about this though, is that I LAST quite a while. I don't usually stop until my back/legs hurt too much. So sometimes I make it for 20-30 minutes. I told her to be careful what she wished for. If we fix this, I might become one of those '30 second' guys!!!!

Thanks
