Can I get an infection from my bf putting his mouth on my nipple one month post- op?

I got a 770 breast implant from a 450 (first implants) one month ago and my bf and I had sex tonight and during he was kissing my boobs and put his mouth on my nipple. (Sorry of this is tmi) but now I'm worried about the hickey he gave me on my breast and the fact that he put his whole mouth over my nipple. I came home and showered with antibacterial dial soap and put some neoaporin on my incision .. am I still at risk for serious infection?
