Hi gidget,
oh yes, my Dh used to have this problem. As the months passed by and he saw how upset I was and he realised we might end up needing medical assistance if I wasnt pregnant soon it all changed. He's very good now, I can hardly believe it!
I think when you start out the male part of the equasion thinks you'll get pregnant if he looks at you but if, and I hope this doesnt happen to you, it takes a while he might change his thinking.
If you are really worried and keen for pregnancy to happen asap I would recommend you talk to him about it after you ovulate, when the pressure is off and tell him about the importance of timing. Maybe find a way to let him know when you are most fertile ahead of time, casually draw a cross or a little love heart on all the right days (add a few extras either side) of a calender on the fridge?
I hope that helps, sassba
