So everytime my boyfriend and I have sex he really doesn't last that long. And sometimes it could be no more then 30 seconds where as other times like 2-3 minutes max! He tells me giving him head before we have sex makes him last longer (biggest lie, he just wants head). The only time it's ever long is if we are wasted. We have tried "Mandelay" which is a gel that's suppose to slightly numb parts of the penis to make it not as sensitive but it barely helps. Can anyone suggest anything!?
