apologies if tmi and am a bit 
I have always been this way during sex. I have no problem making myself come but if my partner tries to do it quite often I just can't let go. they can take me right to the edge and then I start to panic that they will get fed up and bored and then that's it. I just can't come.
is this normal? and how do you get over it?
am missing out here ladies.. please help me 
its really frustrating for me and embarrassing.
