Definately Not!
If you want to hit the “epicenter” as Dr. LIN calls it, try being on top with her ankles on your shoulders. Rock closer, and farther from her. Eventually you will go right past the hard cervix (OUCH) and hit the “culdesac” which is actually called the Fornix.
Mind you, it can be painful for her. Sometimes she will feel it all throughout the lower abdomen. Be careful.
Do this, 9 shallow thrusts (basically just your glans in her) for her and then 1 deep thrust to the Fornix for yourself.
She’ll get off, you’ll get off .. And she’ll think your are huge. Right after, she’ll want it ( I mean really want it) from behind.
Ok, now go practice. But, be gentle. .. Well, until you get into doggy style anyway.
