I was reading an article about sexologist insisting that is normal for a man to be unfaithful...and when a man has sex with a new woman for the first time his amount of sperm triples and spermatozoa increases 5-6 times and they get 2-4 times quicker too... (what a party going on inside! Very impressive!) Wow...how many women do men need to satysfied their need ??? And how many of you guys who are in steady good relationship have this urge to have a new woman for at least a night stand once in a while ? And trully do not feel remorse about that because it was just sex and it doesn't matter at all? Thanks!
