Many men are what is known as hard thrusters.
The most dangerous flaw of all is not even knowing you are one, because a woman you doesn't like this will probably leave you as fast as possible.
Men, are you making love or are you training for the pelvic thrust championships? Men almost never think about whether or not they are thrusting too hard for their women to enjoy themselves during intercourse.
This is a major problem for a lot of women and they often don't say anything about it until they leave you for another man.
So, how do you know if you are a serial power thruster? Well, for the really blatant offenders, there are some simple signs.
If you lover is moaning and her voice is vibrating form intense movement, then you are doing it too hard.
If she has ever hit her head off the head board from extreme thrusts, that is another good indication that you need to tone it down a bit.
Beyond the external physical soreness and psychological damage that this can create, there is also the internal damage that can result to the vaginal canal.
Your lover may experience micro tearing or general over all soreness, and that is not a good thing.
This makes intercourse very painful for women and often leads to shorter sex sessions and sex less often.
Women often need many more days off in between sex if they experience these problems.
The best thing to keep in mind is to remember to make love and not get too physical.
