Hi this may be a stupid question but here we go. Lets say I bit my cheek or lip on a Monday or Tuesday and it turns into a sore should I not go down on my wife like the coming weekend and or kissing. I would guess not. It happens not all the time but more than I wish and of course it's always at the worst time. I've always played it safe and played with her with my hands with sex and no kissing. I always wondered about if it's a bad thing or not?? Thanks.
