Ttc.. Husband sperm count

Hay
Okay we have to test him before they say it is all me the reason why we haven't conceived in the two years of trying. They sent a cup and he has to have the sample at the lab within 30 minutes of doing the sample..... My husband is the most secret/personal guy there is! He is all about not showing any type of PDA... Much less doing that type of sample in the car (we live an hour away) or in a bathroom. Any tips on how I can ease his mind? He is the type that I was worried he wouldn't kiss me at our wedding because of how bad he is ....
