I am so sorry Taylor, it can be frustraiting when your significant other just cant understand what is going on. Maybe you two can come to a comprimise, find other ways of pleasing one another without having to have innercourse, that way he cant say that you arnt trying, bottom line is though at 38 weeks it is going to be uncomfortable and if it isnt something you want to do them he needs to be understanding. Cause once you have the baby your not supposed to have sex for six weeks and what is he going to do then? Ask you to sacrifice because he does? Men have this instinct for knowing how to play the game so to speak to get what they want. My husband did it to me for a little while till I learned how to play back and now we only play like that for fun cause it can cause a rift but non the less no one should have to put up with it. So when he tells you that he makes sacrifices for you tell him that you understand and you appreciate it, but when has he sacrificed his well being and that of his daughters for you and I am sure that you have made sacrfices for him and you just need to remind him of that as well. Sometimes mens testosterone just gets the best of them and they just go nuts when it gets to that point with him, help him get some relief and you dont have to have sex with him to accomplish that. Best of luck to you and crongrats on your daughter, you are almost done and will be holding your little one soon.
