Talk to your doc have him/her tell your man its ok!!! Mine tells mine every visit to keep it up cause it will help and will be a while once shes her so get it now!
I've tried telling him that when the baby comes I won't be able to have fun..... his response is that he's grown and that sex is important but it ain't everything. I agree with him, but I feel like I could explode!
All I can say is learn to help urself. With my first hubby was too weirded out to have sex and the one time I finally got him to try (I practically attacked him lol) my DD kicked him and that was the end of that. Some guys can't get past that its their child in there especially if its there first or their daughter's. I had to get very comfortable with helping my self. There was no changing his mind even my doctor pleaded with him on my behalf and nothing. Good luck hun
