Help! Husband is upset when he can't "perform"

kimmycup

Hi. Sorry to barge in here, but I honestly don't know who else to ask. My husband and I are TTC. We've had 1 miscarriage 2 months ago, and just started TTC again this month. Usually this is not an issue, but every once in a while my husband will not be able to ejaculate. This just so happened to be today (when I'm ovulating) and I could tell he was upset, even though I'm not. I told him not to worry about it, we can try again tomorrow...but I could tell he was still upset. Any advice on how to get him over this? 

Thanks in advance.
