He wants to wear a mask while we BD 😂

So my boyfriend and I are in month 1 of TTC and I’m on Cd 11. He knows that my fertile window is approaching but of course, he came down with the flu a few days ago. I told him we can just hold off until next month but this crazy man wants to wear a (surgical) mask while we do it 😂 I’m still scared of getting sick so idk what to do lol
