Thanks for all your replies. I have since had a big chat to the DH, and he is far more uncomfortable with the whole gender swaying thing than I am. He even said, "I don't want you coming to me and saying, 'you have to have sex with me now' like you're some kind of alien that i need to impregnate to continue the species!" (Lol)....
Hard to imagine a man refusing sex, but he basically said that if its not spontaneous and romantic- then he's not into it!!
He would like a baby girl next time around too, but he's not prepared to participate in any 'contrived strategies' (his words) like eating certain foods, DTD at a particular time, in a particular position etc etc. Gggrrr.
So, I guess that makes it easier for me! Maybe if I just forget about it and have fun- who knows? What will be will be......
