Trouble with Ejaculation

Hi everyone, I need some advice.

My husband and I have been trying to conceive for the last 4 months, currently in my fertile window for month 5. And this month my husband has been having trouble maintaining an erection, and even when we are able to have sex he has been struggling to ejaculate. I talked to him about it and he says he’s just in his head too much because he wants to conceive so badly. It’s starting to get me down, I too really want to have a child - and obviously need the swimmers in order to achieve this!

I’ve been trying to pull all the stops to achieve completion but to no success. It’s of mention that we are shift workers so finding time is always a hurdle.

Has anyone else experienced this? What tips do you have to help? Thanks in advance!
