So heres the deal, My wifes want more kids and Is doing tests So we know whens the besst time to have sex.
But I feel under presser and my little guy dont work like that, I know this must be all in my head as I can get an erction when we are just messing around etc, I just cant do it on demand, and its not helping that after we try, she just gets all ****** off and dose not understand.

Any one had the same problems?
