Sorry am not  a regular reader of Cosmo...  As far as sexua| energy expended on the average for less than a minute, it really does not seem to make much difference, if any...  

Now I know there are some (but very few) super studs who either have a Cocaine high Erection, or some such, but just like the 100 YD dash, you can't physically keep that pace up long enough to be effective... BTW: Sports fans if any male follows such prolonged erections for very long he will be permanently damaged and live out his older years, saying why did I do that!!   Besides only the male would benefit from such activity anyway...  More women want to loose weight or fat so it is a mute question!!

But the fact remains that aerobic exercise continued for at least 20 minutes does in start to burn FAT!!  So if you want to lose the FAT, get on a proper diet...  { Refer to some past posts on my blogs } and obviously have to have some form of exercise beside sexua| Intercourse; to be able to make a difference!!  HUH!!
