yeast infection questions

Okay so I know none of y'all are doctors but I wondered if anyone could help me out because the internet didn't really. 
I got my first yeast infection and it's not that bad but I did have sex without a condom with my boyfriend and now he's super freaked out he's going to get a yeast infection too (we looked on Google and it made it worse) so we both took a shower and cleaned ourselves well. Do you think he's okay or should he go to the doctor too? 
Also, did I make my yeast infection worse by having sex? I found out it was a yeast infection when he pulled out and he's penis was yeasty... I thought the problems/symptoms I was having were from my period. 
Thanks!
