Consent for kissing

I have read on many reddit threads that kissing is by default and you don't have to explicitly ask for it. So if you decided to get/give a BJ or fuck/get fucked and didn't discuss anything about kissing before meeting , do you reach out to kiss when you meet or you ask that 'would you like to kiss' ? I had few very hot guys who gave me a BJ and I never asked them if they kiss. When I messaged them for next time and asked , they said they love kissing. For some reason , there couldn't be a second time but now I feel I missed great opportunities.
