Super embarrassing question but very serious!!!

The other night, my boyfriend and I were having oral sex and he came in my mouth. I swallowed. 
I've been reading that recently the baby is starting to taste everything I eat... Should I be concerned? This is my first time doing this since being pregnant so I'm kinda concerned.
Oh, and I'm 20 weeks today ( yay! Halfway there!! )
Thank you for responding.
