When I have sex with my girlfriend its pretty easy for me to cause her pain if Im not very careful. My dick isnt that long, around 7 inches. I also bought her a vibrator that is slightly larger than my dick, my question is if its certain that she wont be able to take the vibrator deeper than she takes me? Is causing pain equal to 'bottoming out'? For me vaginal depth is a sort of a mystery, on one side I hurt her with my 7 inches, on the other side you hear about women taking much longer penises all the way, please educate me!!
