Nervous hubby...

I stopped my BC a little over a month ago to try and get my body back to "normal" and ever since my husband WILL NOT cum in me! We are not actively trying as we are going to Mexico the first part of February. I understand his reasoning for wanting to be careful as we have this trip and can't can do and the scare of Zika but I tell him I've passed my fertile window and he still won't. It sounds stupid but it's very frustrating and has made sex less personal and romantic to me, any advice?
