So the babe and I have been having unprotected sex for 5 months now ... not that I’m trying to conceive but I just figured it would of happened by now... I have 2 daughters he has 1 ... my periods are a lil off and I have sex often during ovulation time and then my period comes rolling in ... I know I don’t have a problem getting pregnant even with irregular periods but I’m beginning to think maybe he’s shooting blanks... he says things about his penis after ejaculation that has me questioning his sperm count. He has noticed there maybe an issue as well but hasn’t really looked into it... now I know sometimes a couple can take numerous cycles to get pregnant but I’m curious as to what is going on here...
